i have done compression tests for some time over the course of the past year and a half and come out with about 245 across all cyls...

i did one tonight and i had 245 235 245 245...

the 10 psi diff, could that be accounted for by going a little too tight on the .004/.006 lash settings on the low cylinder when i put in the Crower stage 3 cam 2 weekends ago? i can imagine the possibility of this situation grows exponentially when you get as close as i am.
