What I'm suggesting is moving the valve(s) .25 towards the manifolds. That would put the valves in the center of the bore. That gives you more room for larger valves. I think a 2.25 valve would be easy to put in a head with the valves moved into the bore .25. It also means the push rod will moved .25 closer to the block, so you would have to relieve the block like Leo shows on page 79, but 2-3 times more.
Are there any articles or pictures showing what Glen Self has done in moving valves around?
