I have 2 SR20DE's, a 53J V4 (from FWD) and a 52F (from RWD). I intend to use the 53J head on the 52F block, I was under the impression that this wouldn't be a problem, but I've been reading the forums and found out the exhaust valves are larger on the 52F, I'm not sure if this would be an issue, or if there are other differences that would prevent this from being done.
