Quench
I'll just get the head milled once I pull the engine, only looking for half a point in compression to take it up to 10:1.
Plus you guys are saying a .040 quench with magnum heads are really resistant to detonation, unless I run 93 octane it pings at 9.4 - 9.5:1 mind you I"m running a small Comp Xe in a heavy pickup with tall gears so once I stick it in a light car with good gears, higher stall and a bigger cam it should smarten up.
Plus I might be robbing my intake charge with my Exhaust and running a lean condition. I ported the exhaust more than the intake and with these heads that might have been a mistake, especially since the Exhaust duration on this cam is 6 degrees @ .050 longer than the intake. I might actually need a cam with a shorter Exhaust duration than intake.
