I'm sure that cam wants more compression than 10.25. it would help turn on the torque some more. your call for sure but if it were me, I wouldn't be able to let that go. Be sure to check clearances again if you do change it. btw, your current dynamic compression at 10.25 is 9:1. If you do get it back up to 10.6, the dcr becomes 9.3. I got it home tonight and did a compression test. Found 150# one the rear and 135# on the front. I added a little oil to the front cylinder and the compression jumped to 165.

Its done above 50 degrees, all spark plugs out, wide open throttle & approx 8 revolutions or until the gauge stops whichever one occurs first.

ACR vents to the exhaust. I went with the ACR valve because I'm lazy and don't like the effect of a manual compression release venting fuel/air on the cylinder head. IMHO it looks bad.
