Regarding the distributors, what if the distributors turn out to be identical? Does it make it OK to buy for more money from MSD, but not OK to buy from eBay because a (supposedly) US company like MSD or whoever sells it?

I mean, it STILL comes from China, either way...

Both distributors can be seen HERE.

Not everyone can afford the heads you listed... Out of those heads ,None flow that great compared to AFR or TFS heads which are chinese.. Hell some of the heads you listed get their billet from over seas.. i know for a fact Eddie does and Brodix.. There is no reason to knock anyone for spending THEIR earned money on whatever they want..

Now ProComp and White wont get anymore of My money ever since the distributor problem.. I bought my heads from individual people, the guy was scared to use these even after he had new seats, guides, and valves put in them.. because people knock the casting.. but thats not the problem..

Again, to me its QC. IMO

also there is a big difference between saving $20 vs $1000.. I cant justify buying cheap parts to save $20 to $50. But $500 or more. You dang right i will try save where I can... i cant knock someone else for doing the same..

Like i stated before its a crap shoot.. I did my home work and other people buying this stuff needs to do the same... Those that buy the PC heads and just bolt them on are asking for a world of trouble.... mOST OF THE PROBLEMS ARE dropped/broke valves due to crappy springs and retainers . used to be because of some bad guides.

i personally know a few people using the ProComp heads and they running with the guys that have 5x as much in their heads...

Its not just dizzy's that are relabeled procomp stuff, but the fuel pumps, regulators, water pumps, hell alot of guys think their paying for a better product but your just buying a name cause its the same stuff....

I will keep it simple so I don't get any of you be-aatches all upset. I bought a few things from what's his name. Some I used, like the valve covers ( that still leak and do not quite line up right but look great ) and the pulleys ( that I needed to chuck in a lathe and turn true ) some I returned to you know who ( rocker arms because they were visually poorly manufactured ) and had no trouble returning them, and some I threw in the scrap pile ( stud girdles ) because I tried to fix them by grinding the metal the chinese cnc machine left hanging off the locks AND stripped out the threads on the stud. I would not consider any internal part made by pc. And will never buy anything they make ever again. If you can't afford something of good quality, don't buy it at all. Live and learn people, Don't get mad, get even by not supporting these companies. We all make mistakes. If YOU don't , well good for you.

Rock on Cobalt

It does not bother me at all nor do i care what anyone else thinks about how I build my car..(if you think i am getting upset?)

Dont take me wrong I am just putting in my 2 cents.. But if we all agreed to do the same thing well we wouldnt be any different from one another and what the hell is the fun in that??

You have to understand that SOME of these parts you buy with a brand name are made by the SAME folks that make the pc junk in some cases..usually its the same internal parts, just assembled here in the USA.. Which is BS because you are buying the same cheap part, just paying someone here to put it together.. You call it quality or whatever but you are still getting ripped just like the guys buying PC stuff..

like you say, "If you can't afford something of good quality, don't buy it at all."

True but some people are never going to listen.

i am not taking up for the PC stuff and saying hey go buy it..
But its not always junk, and its not ever perfect..

the only point I have is the PC heads have a good casting to start with.. I have already bashed on the distributors, fuel pumps, regulators and what not..

the PC valve covers on my 502 never leaked but the ones on my dads 305 with PC heads leaks like crazy.. Could be the PC heads in his case? They are old castings and old valve covers..

Dually, I really don't know where you get your info from but Edelbrock pours all their products at their very own facility in California, San Jacinto to be exact. I have been in that plant and the machining plant. Last I checked, California is in the USA.

Brodix has been pouring and machining their own heads in Mena, Arkansas since 1971. Again, Arkansas is in the USA, no?

The billet blocks they melt down and use in all their manufacturing comes from china....

Most of these Companies buy their steel and aluminum from overseas..

Hi guy's, the Procomp heads ran strong all this summer shifting from 6500 to 7500 rpms I had no problems. I bought the heads 4/15/09 I'm very happy with my set up the motor pulls hard and even hard when it get around 6600 rpm like nos is hook up to the motor - not sure why the motor kicks harder around 6600 rpms but man the kick or rush have been getting me to win few races with in the class I been racing in. The car is 82 Camaro with 327 30 over motor 4 speed M22.

Other procomp items I used - valve covers 4 sets I have never had a leak, 3 mini starters over 3 months time I thought they was bad do to over heating but come to find out my push to start switch was not letting enough volts go through I replace the push to switch with 50 amp toggle switch all 3 mini starter work man.

Glad you've had such a good result from the parts.

AFA why the engine seems to pick up at such a high RPM, I can only imagine that either you have a hell of a lot of cam, the secondaries are late opening if you have a vacuum secondary carb, or the advance weights are sticking until you reach that RPM or the springs are way too stiff. But more likely something mechanical to do w/the distributor advance or late secondary actuation, if I had to guess.

I'm not sure why but man it runs good a 327 running 11:18 / 11:22 in the 1/4 mile.

My carb is quick fuel 750 my jets are 76/85 if go smaller on the front jets mids drop some. "O" the manifold is black rpm air cap with 2" spacer. It still pulls strong from idle but when it gets to 6600 rpms pull much harder.

"O" something els if there's 3 other people in the car seems faster.

I have 373 in the rear with 28 x 11 tires on the car.

I bought Procomp 190cc 64cc heads assembled from kmj on ebay for $619. I also bought 1.6 stainless steel full roller rockers for $129. I've been running my parts about a yr and they perform flawlessly. Noticeable perfomance increase. about 8500mi so far. I did not like my Procomp 140gph electric fuel pump. It was to noisy. I had been wanting to put a pump on my motor anyway. I bought a Victor jr 130gph. #1711

i can't remember if i had posted this under this topic or not, so here it goes again.

i bought a set of procomp big block mopar heads, rockers, valves, valve covers, & valley plate about 4-5 months ago. the only thing worth keeping was the heads. the heads checked out great, but the rocker adjusting bolts was drilled at an angle so that the adjusting nuts would touch on one side & have a .025" gap under the other side after they was ran down on the rocker. .025" is massave on something that simple that should have rested flat all around. the valley plate holes didn't line up with the holes in the heads, the valve cover holes didn't line up with the holes in the heads. the valves was cheap low performance valves.

now as far as what everything looked like, it all looked very good, until i got checking basic stuff.

i even told the guy over sales at procomp, if i liked what i got i would be sure & praise the hell out of them, i also told him if i didn't like the parts people would hear that too. i guess it didn't matter. this wasn't old stock being pawned off on ebay, this was their current run at the time.
