300ex Head

[Kurly154]

Does anyone know if a 300ex head will fit a 250x? Are the valves the same size? And where can you get your head ported and polished pretty cheap? Thanks

Yeah it will work. Porting and polishing is usually not cheap at all. It really depends on how aggressive you want it done, and most shops will charge about $45 an hour.
