Got a new build but trying to figure out which direction I need to go, I have a set of the MAST 255s ls3 heads now but also have a set of the BMP WARHAWK LS7 heads. I am going single turbo 98mm gen2 pro mod on methanol and now with the ls3 heads its at 13.1 compression with the 58cc chamber and the ls7 heads are just 64cc chambers so not that much difference. Motor is a 427" lsx so any good info is appreciated.

Either head should allow you to max out the turbo.

I would check with whoever is going to tune the car and get their recommendation.
Others will chime in too.
