These are our completely new dual port stock replacement cylinder heads, They offer these heads with the quality stainless steel valves in both the intake and exhaust. The intake valves are 35.5mm and the exhaust valves are 32mm. When replacing a head it is best to do both sides so you know the heads will match in the amount of cc’s the chamber has, if you replace one, and the one you are keeping has been fly cut then you know the chamber cc’s will not be the same on both sides. They are sold each.
