Looking for more HP from a 360

Truthfully I dont think I'd go full custom just yet. But, the spitfires are a header compromised a bit to fit. The TTIs would be a header compromised less to fit and would support a bit more power. Full customs would be the best but they will be made for this plant... not something I'd spend the big coin on. I don't run the HVs unless the bottom end has issues. I'm a firm believer in windage trays even on strokers, but I tweak them a little to open up the escape paths.
