Trx 300 mods

Does anyone know if the 4 valve head off a 300ex will fit on a normal trx 300 engine??
How much more power does the 300ex have than the standard 300??

Thanks for the help

The 300ex makes about 17-18hp. That head can be nice. It has small valves and needs porting but with some work they can flow. Couldn't tell if it fits though, sorry.

i dont think it would work being that youd need a differnt cam
