I contacted NCY and there prices are nice and low. They have a wide variety of parts including the 4valve head. Also there service is very fast. Soon i will have a few parts on my wish list.

Do you think that the 4valve head will be better than a 2 valve large head?

for an aircooled engine i'd rather have the 2valve heads b'coz the valves seal better at high temps than a 4valve head, the bridges between the valves on a 4valve head are thin & they warp slightly when they're hot so the valves don't seat well.

for aircooled 4stroke race engines nothing beats a 2valve setup in terms of durability, in Pro Stock dragbike racing the 2valve head engines are the reigning king.
