on my pistons i had to get both the exhaust and intake reliefs changed and i was still using stock cams, ive heard many people say you only need to change one side, i highly doubt that to be true as i had the valve hit the piston on a test build, i used precision (american) hyperuretic 3T pistons, give me a day and ill dig up the values we gave the guy.
