heads

stroke,
This guy is one of my best friends. We have been friends since we were like 8 years old and grew up together. I know he wouldn't try and stick it to me. He bought the bare castings from jegs, and had them assembled at the local machine shop with all comp and manley parts. he's got right around 800 in them. The main reason he switch to the AFR's is cuz they were free. His mom and dad are loaded and he just had a birthday. They didn't know he had already bought the PC's, but thought he was still needing a set so they got him the AFR's as a b-day present.

I wish i could get a present like that, used to be lucky if i got a card with 20 bucks in it, now, i get nothing my baby boy is the one getting spoiled. But that fine with me, I'd rather work for my stuff anyway I'll appreciate it more and take better care of it in the long run.

This same friend also has a set of flotek heads just sittin around that actually used to be his dads. He had them on a 350 in an s-10 that threw a rod threw the side of the block after the 4th or 5th pass, with a 300 shot of nos. His Dad never build another motor so thier just sittin. I was told they were the same chinese casting marketed by TSCH, but i really don't know for sure. Those flotek's came with all the valves and hardware already in them from god knows where. thats why I wanted the PC's instead, the comp components and manely swirl polished valves. I also said that wrong, I don't just go with anything aftermarket. However, these heads on my engine will take my CR from 9.7:1 to 11.1:1, and they have the larger 202 intakes, and a larger, cleaner 210cc intake runner that will definitely flow better. I did actually ride in his truck with thoses heads on it but it was WAY out of tune thats why i really couldn't tell but he said it did very well once he got it all lined out. I know they aren't gonna be as good as AFR and i don't expect them to be. I am really looking to pick up around 50 HP, I'm prolly around 375 hp right now, if those heads put me at 425 HP and 410TQ i would be happy. Any info would be great, thanks

'Most anything' aftermarket does not mean it is any better than oem. There are thousandss of 'aftermarket' parts that you can waste your money on. Personal friend decided to buy some 'aftermarket' roller rockers for his BBC street/strip TA. Well, those pretty, and cheap, rockers lasted a whole 400 miles. They are called ___ ____. I'd be wary of any 'good' heads being sold for $400, especially 500 miles 'new'. If they were any good at all why did he change them after only 500 miles??? I can assure you, his AFR's are in a class beyond the realm and reach of those el cheapos, even if they are old AFR heads. This is just typical... IMHO

stock

by the way I dont expect the world from the, Just somthing a little better than what i got which are the stock 69' chevelle 350 heads with 194/150 valves and 76cc chambers. I think most anything aftermarket would be an improvement if they work.

heads

Hey I was just wundering how long you have had this motor running with those heads and what kinda power it had. I got a buddy thats trying to sell me a set with around 500 miles on them for $400 cuz he went to AFR instead. Seems like everyone bashes them cuz of where they come from, but its hard to find info from folks that are actually using them. Any numbers would be appreciated, HP, TQ, Et's MPH in quarter. thanks

Thanks for the post and link 406...

Just pulled the intake and NO OIL in the intake ports....looks like the intake was sealed just fine (was a pain to remove). It looks like I will not getting the intake machined and I have no idea where the oil is going

I don't have the coin to start swapping out heads and intakes due to the $ I have invested on this new engine
See, if you had invested the money wisely I doubt you'd be having these issues. Just because the parts were/are new does not make it a worthwhile investment. Like said, cut your losses. What would be the big deal to remove those heads and sell them to another sap, and get yourself a set of heads that are known to be worthwhile, an investment, both in time and money.

406 ss monte i've never seen the procomp heads, but have heard both good & bad about them. pull your intake & look at the gaskets. you should be able to tell if their getting squished equally. do they line up with the ports on the heads & the intake? intake gaskets come in different thicknesses, maybe something to look at?

this link might be able to help. ask these guys, their using them.

I planned on smeering a light coat around the intake ports, and water ports and installing the gaskets letting that stand for a few minutes and then installing the intake gaskets and smeering a light coat around the intake and water ports ? I also planned on using the ATV on the front and rear of the intake (ditching the rubber or cork); which seems like common practice. Thanks.
RTV does not mix with fuel, unless it specifically says it is resistant to it. You only need to do the water ports.

Just wondered if others experienced similiar problems and if there was a solutions.

Thanks techinspector on the article on getting the intake machined..

Sounds like the problem is more of the heads than the intake......

Since you're contemplating an intake purchase, may I suggest that you ebay the scrap aluminum that you have and buy something else from a reputable manufacturer? Even if they're cast iron, Dart, World Products or even Summit stuff you likely gain horsepower and have no more problems. I know this isn't what you want to hear but the fact is that you'll spend more to correct this situation than it would cost to just eliminate it altogether.

instead of doing that you can just cut 2 strips of steel and bolt them on one end so they can swing back and forth and make a V shape. Line up the sides of your tool with the bottom of the V in the lifter valley and the outer sides of the V against the heads where the intake gasket goes. Once the sides of the V are flush with those sides of the head use another bolt at the bottom of your "tool" to tighten it up. That will give you an angle that the heads are at...then you can take that and compare it to your intake
09-16-2008 05:10 PM
techinspector1 OK, then take the heads in and have a very light cut made on the intake side, just enough to see that they're parallel, then proceed with the exercise that I outlined.
