Ok guys does anyone know of any place to get ported heads with single piece valves? Most places I look still use the 2 piece valves even in there performance heads but every shop I talk to says a good build should use single piece and seeing as how a valve is what broke I can see why. So if you know of any good places that sell ported heads with SI single piece valves let me know. Otherwise I think I will get them custom done around where I live.
