I spent the day today milling, grinding, CCing heads, and checking valve clearance. I have the heads down to 2CCs difference (114 and 116). The valve clearances are FI: .150; FE: .090; RI:.175; RE: .090. The head with the larger chamber has the lower Intake clearance. I am leaning toward leaving well enough alone and not messing with them any more.
Comments, ideas, opinions, please.
