    does porting your valves 1mm over make a difference in overall performance and flow?

    i talked to josh from dh-racing and he said that using 1mm over valves was dangerous and didn tmake any real difference...........he siad that there is a risk of your valves hitting?

    i am using crower 297/287's, so i didnt that that i would have any problems with the valves hitting, i just thought it would help the head flow better!


    someone with some knowledge or experience with this please help!

    thanks


    also, does anyone know if i could send my bare head and all the internals i purchased to portflow, have them do the pnp, and then them assemble the head?

    that didnt come out the way i wanted it to. what i was trying to sya was would the 1mm over valves make a difference with the port n polish, not the valves themselves ported.

    sorry about that!
