The outlay for the guides is not all that expensive, go with the 11/32, you will be better off this way. I gave my set of 3/8 guides to Alan, as they were no use to me for what i had planned.
There is a multitude of potential, take full advantage even with a smaller valve, remember to locate the intake valve in the best location with enough room to go larger for a future overhaul if the oppertunity arrises Brad

i would be interested in measurements and progress as you go with yours if you did not mind sharing the info please
