Might want to mock it up & see what the deck height actually ends up being as you can then mill the piston deck/valve reliefs for VP clearance/less CR if need b then dissassemble & have it balanced and depending on your octane you may want to adj the CR but w alum heads you can get by w (& prefer) higher & I like to b able to max the adv curve WO having to compromise it cause the DCR is too high for the octane. Good Luck & holler what CR it ends up being and how it ends up running for you
