I have a 231 237 .598 .596 cam 114 lsa and don't want to flycut what heads should I get? Car has 4:10s lt's true duals pulley and will install ls6 manifold. I would like to be in the 430 to 450 range without reving to 8 grand this car will still be driven on the street.

 

Stage 1 Patriots should work, or any ported head with stock valves..
