If it looks that good I would talk to a machinist and see if you could just slide in a set of KB Pistons for around $300. I ran close chamber 915 with flat tops 10.3 to 1 ran great on 93 with a nice .039 quench
Most kbs I've found were around $469 or more thru summit then another $300 in bearings and rings $550 for a balance job just for a little bit more compression. Would it really be worth it? I was actually thinking spending 80 bucks and get a little shaved off the heads and as small as the combustion chambers already are on the stage 6 heads even shaving .010 or .020 or .030 would reduce the cc a decent bit and still leave plenty of meat for future milling.
