Because my exhaust valve has .130 clearance, its fine. I am worried about LATERAL clearance on my intake valve. The side of the valve it close to the side of the valve pocket. It looks as though it has .050 ish clearance. I just dont wanna fuck up. These are new pistons. Reliefs are different.
OK, now I'm following along. I wouldn't think you're going to get that much expansion of the relief area when it heats up to create an issue? I'm sure someone has experienced that and can chime in and give a better answer than mine? Worse case scenario pull them out, and have the relief cut back a few thousandths before you do your final assembly?
if its not assembled yet......dont chance it, id get them cut larger, Mine were about .030, i put it together and guess what?? every intake left a witness mark on each piston and it was getting oil in the puke tank. Why chance it?? .050 is prob ok, but after my exp i had them all opened up another .050
