Highest flowing sbm heads?

All this stuff is mid 11’s compression and pump gas friendly.
mine isn’t, because I had my heads milled for a little extra compression because I like running 110.
The 6.08 motor is 11.6
compression dyno’ed on pump gas
Trying to get this thread back on track, what would you guys spec for a 700hp 416 ci pump gas build?
Bloomer heads made 657 and 680 hp and have ran well at track. Add high compression or keep it pump gas and maybe find a m1 tunnel ram. Just a thought? But anything 600-650 pump gas should already be plenty lol
