RBD Posted September 14, 2006 Report Share Posted September 14, 2006 There are not much differences between the Y-1 and the Y-2 heads. The Y-1 heads are off the earlier Banshees and the Y-2 heads are the newer ones. I can not remember the change. I do like the Y-2 heads better because I think they are a better casting and the combustion chambers seem to be more centered to the cylinder. I also like the water jacket a little better in the Y-2 heads. Both the Y-1 and Y-2 have the same volume domes. For those that don't know, the Y-1 and Y-2 markings are cast in the top of the heads just under where it says 2GU which is where the small hose is that comes out the top of the head.

I learned something new today. Thanks! :baseball_original: Quote Link to comment Share on other sites More sharing options...
