Hey, I was thinking, Why doesn't someone make domed valves to suck up a few of those extra CCs? I was told that some guys were welding up their combustion chambers. That sounds a little risky to me without a furnace. I have "Dropped" my spark plugs down about .030 for what ever gain that will give me. Jes thinkin' bout it!
