Photos to come.

Just curious - how did you decide on 9.5:1 as your CR? That's really pushing the edge as far as boostability...you'll likely have to run pure (i.e. don't blend with pump gas) VERY high octane race fuel ($$$$$$$$) if you're planning to make a lot of power from your boost.

Before you bolt on your head, consider a thicker-than-oem headgasket to help compensate for this (to me) overly-high CR.

Also, before you bolt on your head, consider modifying your block for 1/2" head studs OR be sure to get L19 studs. Oem-thickness regular ARP studs won't hold 40+ psi of boost.
