Ed, if keeping the stock size exhaust valve instead of going to the popular 1.4", do you think it would be possible/beneficial to go larger than 1.7" on the intake?
im not going to say yes as i havn't got to play with it yet but lets think about this... my head ported by a Nor-Cal slant guy flows very well, but damn near even on both sides with the 1.7/1.44 valves, that should tell you something.
I finally found someone in phx who has a bench and is willing to do a head for me. The plan is a 1.9x or larger intake valve and 1.44 exh for the next race head. i have to look into some other stuff as well such as valve angle and surface angle, may be messing with that to
