Sky65 Well I got the heads. They are "brindled"? One also has a steel insert in one plug hole installed from the combustion chamber side. Not what I was expecting. The machine shop says the plug insert looks ok and he can mill the head gasket marks out. He would recommend at least "cc"ing them after the mill just to know you end up with. He would also recommended a tear down, as you all did, and check it out. I need to call the seller. I'm not sure if I want them in this condition. Not what I expected for "less than 200 miles".

cool rockin daddy Sweet Vette. My guess is you'll pick up 30-40 HP over your stock heads. And at half price? I 'm jealous.

bentwings I have RPM 70 cc heads on my car. I drove it about 1500 miles before the blower and they worked great. 12,000 with the blower so far, same gaskets , same plugs. I do use head studs which require engine removal to service the heads. My choice however. Mine were new but purchased at a very long deal.

There should be a number on the front of the heads. From this you can go to the Edlebrock site and find what cc they are.

With an Edlebrock RPM cam and roller rockers you are limited to about 6500 rpm and about .560 lift. More than enough for the street. The RPM cam needs a 3000 converter to be really easy to drive. I tried it with a 2000 converter and it was possible but not real easy.

They are very street worthy and limited race use. They seem to buy some leeway as far as gas octane.

There are at least 6 users of these in the groups I travel with and nobody has had any problems at all with them.

Be sure to use the correct gasket. Check the Edlebrock site.

BTW the matching RPM manifold is an excellent choice for the street. I have an Air Gap that I originally used. It worked really well but it's not the best choice for Minn weather. The standard RPM manifold will make the same hp with in a couple and be much more drivable when it is cool with the heat riser port.

I also used a Holley 3310-3 carb. It took all of the tuning aids to get it where I wanted it but it worked very well. Even got pretty good mileage. Funny thing is that the exact same motor with the 6-71 blower and 2 750 dp actually gets at least as good mileage.

327NUT Reminds me of my brothers '63 split window ...but he sold it back in '68. It was a theft recovery, it was cherry but missing engine and trans. We built our first 327 for it, 4 spd., we glassed on fender flares and my Dad painted it marina blue laquer (gorgeous!!!). Installed REAL American magnesium torque masters with Firestone red steak tires. Turnred out very nice, like I said he sold it a couple of years later.........for $1700!!

F-BIRD'88 Not enough O's in S-M-O-O-o-O-T-H to discribe your vette.

The car is a 65 vette driver with a 69 350/350, 11:1 comp, currently 186 heads 2.02/1.6, Hooker sidepipes, Richmond non-od 5sp with 3.08 rear. Right now has Edelbrock EPS manifold with 750 Demon but going to Edelbrock 3X2 intake with small base Roch carbs, progressive linkage. Also going to a Howards retro roller cam, recommend here.

mainejohn i just put a set on my 355 and just broke in the cam. they seem good but the road here are muddy and 4 feet of snow, so it will be a month or so till the roads are driveable. living on a main dirt road sucks.

Leoman These heads are advertised at 185cc port volume, which ought to be ok for a mild build. I haven't used them because I'm a bit allergic to aluminum (I hate helicoil), but one thing I'd be sure of is that they haven't been brinelled (indented) by the head gasket rings, particularly if your intended new gaskets don't match up to the indentations.
