I have been doing research on your heads and using them for many yrs.. I have a 540 cid BBC that is built for my twin 98mm precision turbos. I have a solid roller cam in it that is a custom ground .930 lift. I need to come up with a head for my setup so I can purchase my Pistons. I have a street driven 1988 Monte Carlo SS pumping 2500hp it’s going in and I don’t wanna loose power. I do drag week and run around at the drag strips I run EFI e85 fuel. Here is a idea of what I’m doing and have.
Jason,
If you want to try to hit your goal with a conventional head I would look into the BP BB-3 XTRA 380 fully cnc-ported 24° cylinder head. You may want to also look into fitting them with titanium intakes and Inconel exhaust.
Thanks!
