So... after pulling a few head bolts while changing my cam, I'm pulling the head off so will rebuild when it's off. A VNT-17 is going back on and stage 4 tune. I plan to put ARP studs and remove the intake manifold butterflies as they a known failure point and ruin otherwise good engines.
Any benefit to removing the web that splits the intake runners and head ports? How about any other head mods beyond deburring considering the relatively modest power bump the turbo and tune will add? Someone once told me head porting can yield the same power as a VNT-17 with the KP-39 but I'm not sure if I'm ready to believe that.
