11/32 valves in X heads

I kind of suspected that he was wrong about the +.100 chevy valves. When i asked about them, the answer he gave was that the assembled height would never be right,if the stem tips were ground down the rocker would hit the retainer and not the stem tip.

A +.100 Chevy valve is only .031" longer than a stock Mopar valve. That's not much diff. I didn't measure is but I'm sure there was alot more than that on most of the heads I assembled. I only had a couple cases where some aftermarket rockers hit the retainers and that's because I was using larger diameter than stock retainers and aftermarket rockers. Stock parts has alot of clearance.

BTW: I just noticed you said the heads have new seats. If that's the case it's very possible that the +.100 valves will work perfectly without even grinding any off.
