Are the valves the same size on the Maxima N47 as the Z N47 head? I know that the chamber size is smaller, but are the valves the same size as the 280 or the 240?

Zhome.com list the N47 as having the same size chamber(44.6cc) as the N42 maxima head.Valve size is listed as the same as all the late Z heads.The only real chamber size difference is listed as the E31 head with the small valves and a 42.4cc chamber.These are of course Zhome specs so you may want to look around to make sure.

The only difference as I understand it is the intake ports are better on the maxima. The design allows for better swirl. There is a n47 head from a maxima on the parts page , titled high compression head.

The intake valves on the Maxima head are 42mm compared to the Z intake valves of 44mm. The good news is that the exhaust valves are the same for both heads-35mm
