if it hits the valves, or head, it is a bit much...this is a hard question..unless you can heat the parts up..trying heating a piston in the oven, minus rings..see how your combo handles it..lots of fun games to play, while learning at the same time..remember, its the difference in temps that counts, not the "as-running" temp...70 degree block, 200-300 degree piston...
i'd say anything over .010 is ridiculous..cold..
