I would think that anything over .600 COULD be at risk. I ran a .605 on the intake, .581 on the exhaust with pop uu TRW pistons and had, if memory serves me right, .100 clearance.

The only safe thing to do if you need to run maximum lift is to measure the clearance with clay.

The NASCAR guys run lifts up near .700 (.680+) but they flycut the pistons for clearance. They say that you need to do that to make 600hp but from what I have seen with the Desk Top dyno there isn't much to be gained in a Cleveland over about .581.
