Thanks,guys!! Kevin...You are 400# less than me!! No heads up! John...You are so right on the balancing act!! I will call tech at Mancini when I have the time...Curious about compression ratio with my 80cc heads.. I have a lot of irons in the fire at this time with dad passing on and a boatload of OT at work..I am scheduled for 56 hours this week and 66 hours next week! Ted
