I have been unable to find a straight answer. Everyone is saying something different about every cam i comes across for the USDM EJ25 (avcs compatible). I know there is kelford, DPR, Cosworth, Crawford? (ughh), and maybe others. I would love to run cams but nobody seems to have the answer. The only thing I have against material added is the safety.
Can anyone tell me which cams are not material added and which ones are?
