I don't remember where I read it, but when you change compression noticeably, do you have to adjust your clutch?
I've been thinking about a high compression head to get some low end and a bit more top out of my Pinto. I've only currently got a Tecno Boss on it and it hits about 37. I just don't want to crack the case to adjust the clutch.
But how much change in compression is needed to adjust the clutch if adjusting is necissary? Because I've been thinking of either getting a flat milled head or just slightly milling another head.
