I am rebuilding a 1970 455. I was curious if anyone had any info/experiences with Pro Comp heads. Have heard some good and bad stories, not sure what to believe. I want to go with aluminum heads, thought these might be comparable to Edelbrock heads.Thanks...Greg

 

Go to realoldspower.com, you'll see posts everywhere on them. They're fine.

I agree with SBOrule but I have yet to see any results from them. Yes there are threads on ROP but I don't see any track times or dyno numbers from a set. I'm more interested in Brad's heads if he can ever get some in peoples hands.
