Hi, anyone know what kind of tunning i will need to install this head on a completely stock motor? obviously carb tuning, but will i need to re-jet them ?

also, what domes should i use for pump gas and how will this affect performance. I hear the 800PV motors do not like too much compression or kaboom !! :nono
