I will mill the head probably .080 and make sure block is square and flat, BUT nothing performance really, rather than just a little more power than stock for seat of pants giggles. Hardened exhaust, have Oregon cam guys do a good torque regrind, solid lifter engine. Very small giggles!!
I have a few blocks that are standard with a little ridge, far as I have gone, I have no place to work right now atually. Sad but true. Shed is too full to move in.
