Look at grind #51. http://www.oregoncamshaft.com/Hydraulic-Cam-Specs.html If Ken can grind that on a 106, that would be a nice one. That'll help get cylinder pressure up with a stock engine, not require any machining on the heads, you can use the dirt cheap Comp 901 springs and it'll have a noticeable idle. It'll pull hard, too. He may not can do the 106, but I feel sure he can get it down to a 108. If he can do the 106, let him do it.
