With 370 cubes I would consider rectangle port heads due to bigger valves and increased flow. Could probably get some CNC for less than what you could sell your nice cathedral heads. And if you ever went to more cubes, I think you would already have better heads with the rectangle ports.

I'm pretty sure TEA ports those.

If you have an engine with a 3.9 inch bore the LS3 heads won't fit unless they are small bore versions.

Brian Tooley did mine. Is there much benefit to porting heads on a FI setup? Surely one just turns the boost up a click??

Porting stock castings, yes but diminishing returns with aftermarket heads that flow well.

Whatever gains you make NA are magnified under boost.
