I am going to be putting together a 427 LSX that is going in a 65 chevelle. It will be a street strip car, leaning more towards street. I am looking at running world products cnc ported warhawk ls7x 6 bolt heads, but am wondering if they will be to lazy down low for street use and should consider something with a smaller intake port to increase velocity at lower rpms. The car will have an Bullseye S480 and be a blow through setup, cam will be about 230 deg@.050 and .630 lift with 8.8 comp. Any input would be much appreciated.

Trickflow 235/245 6-bolt heads on LSx blocked deal for the money.

You'll be just fine with that engine even out of boost. I see no problem merging into traffic.

the warhawk heads leave a little to be desired.As said above i would go with the TFS 245

Turbo is too small or motor is too big IMO. It'll be a torque monster but run out of breath early.
