Skulled J head

... Ideally you make the skull to a preferred spherical shape, then the pistons (although they could be ordered simultaneously, with a final fit), then all the finishing work on the head so as not to have the guides and seats move around, but I bet they will still move some if that much of an extensive modification. But if you have to fit the valve notches very precisely (you can't always have the piston manu do this, at least not the depth) the valve job would have to be finished ahead of the pistons. Fortunately skulls don't seem to be necessary in Pro Stock.

Aaah ,I got ya....So with this cyl. head your pretty much stuck with this chamber then.....Not that there`s anything wrong with it.....It just seems that doing the skull work would be done somewhat last....But I understand what your saying.....

Don't know, don't care! It's Kawi stuff & I am a Suzuki guy! I just wanted to find out what it is worth. Ray.
