I don't get the remark about water?

No need to apologize Ed, not only do we look forward to it ..but we all appreciate your input. You are a lucky man to have raced in the junior stock era and still be more than competitive in today's Super Stock eliminator. In the Don McElroy era, he would bolt a dummy head on the motor and with the assistance of a BFH he would hammer the valve into the piston.

No, it is not legal to cut the valve reliefs on pistons in NHRA Stock Eliminator.

I would probably consider 0.060" piston to valve clearance on the exhaust to be the minimum safe clearance, if it was properly checked to begin with, and you have very good valvetrain control.
