The BOP 1-piece gasket is a "godsend". It really DOES "work". It fits all three "designs" (the cork strip is far and away the BEST of the factory designs).
I posted a procedure for this on Bill Boyle's site (pontiacstreetperformance.com) where you asked the same question. I have recently sent Bill an "article" I wrote concerning "sealing up" the whole Pontiac engine, and what pitfalls to avoid. He has not yet put it "up".
