yea ive seen that one......the problem is the ls7 are known to be high end happy and at decent at best down low but from what i have seen without a ton of effort, the ls7 heads are nothing to write home about down low......i will look for some cathedral heads designed for 4.1 or bigger bores and see what i can come up with.....the ls3 heads however tend to be better down low from what ive seen than the ls7 heads and can be very decent up top.......so i should switch the topics to large bore cathedrals vs my current heads.
max static compression would be very important here as would low cam duration. Also minimal overlap of 3 degrees at 0.050 in. lift yet a big lca like 116 or 118. Alao run the cam advanced 4 degrees. more lower end torque!
