Found a few people asking this same question....no answers.

I need to order gaskets.

LQ9 370ci or 390ci, 18 psi boost, ARP head studs (not 1/2").

((I haven't decided on 370 or 390 yet, I'll make that decision on Wednesday when I drop my block off at my builder. But I don't think that matters to my question.))

Thanks.

so if going with a 370 or 390 the ls9 gasket should fit just fine..
