Old thread I know but I see VR have higher comp. can anyone tell me the difference in the heads that makes the VR higher comp? I have a couple of what I think are VP heads and I want to have them tricked up to suit VR plus maybe a tad more comp above stock VR.
Excellent, I will have no issue then using the heads off my spare engine on my DD. I'd like to have some reshaping done and it will be better if I don't have to wait to have the heads recoed and ported.
