Talking compression?

Im kinda in the same situation. 360 isn't built yet but I have some KB191s. Talked to UEM on the phone and they reassured me I can mill the dome to the same height as the quench pads for 10.5:1. Looking real hard at Comps big mutha thumpr. The duration would drop dynamic compression enough to minimize or eliminate ping on 93octane I think. Any input??
