I am looking at these heads on ebay. I am considering putting putting them on my 350 w/flat top pistons comp 270 cam in my 67. I want to replace the 441's that are on it now. Any experience out there with them? The price seems right. I don't want anything with too big of ports so there is no low end. But I may build up another short block that I could bolt them on to that would run higher then the short block I have.

I could not find these heads on ebay but, 190cc intake runners and 64cc combustion chambers, with flat top pistons should get you 10:1 compression and work good for you. These heads would also work on a 383 but you may want bigger runners like 215cc. As always just IMHO.

But be leary of these cheapo Pro Comp brand anything. They are not good quality as I have heard. They are cheap in price and may be worth trying out if your short on cash??? But, I personally would probably stay away from them for the few hundred bucks your gonna save. Sometimes a dollar saved with cost you more in the end! I see deals on ebay all the time for good brand name aluminum heads. Like they say. If it sounds to good to be true, it probably is. You get what you pay for! Good luck.

383,270 Cam, and 190 cc heads ? Not a bad combo IMO.
I had a 280 Cam and 200cc heads on a 406 which worked very good IMO (12.37 @ 110) Now same heads and a solid roller (untested)

I noticed not to long ago some heads on ebay called patriot however they were not the Patriot Performance products.
They were knock offs from china.

Summit has complete aluminum edelbrock heads for under $800.00

Rich, Which edelbrock heads are under $800.00? I've not seen them for that... cheapest edelbrock's I've seen are $510 each.... that's 70cc / 170cc.

I have the pro comps on my 383. They seem to work really well. The cast finish looks nice. If you buy a set, buy a set from a reputable cylinder head assembler. THe guy i bought mine from initially told me he got them from RHS. He lied. They were cheap, they seem to make really good power with my combo BUT the quality control sucks in my opinion. I dont think i would take a chance and buy them again but I should put them on a flow bench cause I bet they flow good. I had to port match my intake to the heads and widen the intake ports to match the width of the intake or there would have been a big dead spot. I used a 1206 intake gasket. I had to clearance #4 cylinder rocker arm to clear the spring retainer on the intake IIRC. Something was off there. Also from cylinder to cylinder there was a difference in either valve seat depth into the combustion chamber or the spring seat itself. Cant remember now. I have 9.7-1 comp ratio with a XE274 cam, vic jr intake and 750 VS Holley. Nothing really fancy but i have a lot of tanks of 87 octane through it with no problems and i beat the crap out of the engine. So far no problems. I run 34 degrees total timing with 47 IIRC with the vac advance hooked up. 15 degrees initial. I often wonder if there will be guide problems at say 10 or 15 thousand miles but so far so good.
