People shudder when you talk about milling .100" plus off blocks and heads, but stack it up on a feeler gauge. LOL It ain't a lot when you're talking about structural integrity. It sure does help compression, though.
I think Tim would shudder at the price to mill .100 off, on this build, with the budget he is aiming at. If he was closer, I'd let him do it on the van norman 570.
