Your best bet is to contact your engine builder so they can have all of the specs and recommendations,

Assuming a .038" head gasket, your SCR is 8.6:1.

.020" MINIMUM top
.022" MINIMUM 2nd
.015" MINIMUM Oil ring rails

I'd shoot for .022" top and .024" 2nd.
BUT....I agree with moe. Your engine builder should confirm.

Don't be afraid of a little extra gap for insurance. You will NEVER see any ill effects from it!

I don't think you will see near 17psi. 9-11 more likely.
