My 1972 Project has its original block (The original block is over bored 30) but realized yesterday during motor tear down the heads are not correct. Has 333882 heads. Looks to have the original cam and intake as well. The cam shows enough wear that I feel okay replacing it as well as replacing the heads. What combo would give me more HP and still not break the bank as I still have lots more to spend money on during the restoration. Needs to run on pump gas and LOOK as close to factory with the hood up. Would like to maintain a relatively smooth idle.

Thanks, Dean

You may want to move this to the tech/performance side. More likely to get an answer there.

Thanks...I will repost there. I did not know there was a motor section.

I looked but I don't think that you have moved the post yet. To start off the 882 heads are junk. Start looking at something like Vortecs or other GM fast burn heads. shoot for 9.5 or 10 static compression. Then get a good mid-range torque cam. Start tuning.

After talking to a local "speed shop" He suggested a Comp Cam CL12-242-2 cam. He thought the 882 heads would be okay for what I want.
Although I have not read one good thing about those heads. I am wondering about the DART IRON heads with 2.02 intake and 67cc chamber. What would I expect from this cam and higher compression heads??? Is it a waste? Would another cam be better but still have a smooth "ish" idle.

If your not building a street racer / race car the 2.02 GM heads are fine for most peoples purpose . Look for older set that will yield a higher compression.

Understood...my issue is the cost of the "older heads" PLUS cost of machine work to add harden seats and valve guides equals or betters buying aftermarket DART iron heads with much better flow. I have ALWAYS been a factory guy when it comes to Corvettes. But in this case staying factory will not only cost MORE money but give me much less horse power as well. I'm really at a loss as to what to do.
