May I ask why you needed to go with an 18 bolt head?

I know you’re gonna run boost, what head gasket are you going to run?

Best of luck on your build![/QUOT. Because it's the way to go. I ran 20 psi with my indy head's before I hert it and had no problems . It made around 1000 hp. I want to go higher and with 18 bolts and mls gaskets it should be no problem.i hoping for 1300 out of this new combo.
