Q: I'm chasing compression and trying to eliminate ticking. Can you help me adjust my valves? EFI SBF roller block

asked by on

I just replaced head gaskets, lifters, rocker arms, and pushrods on my 331 stroker SBF and I had a tick coming from the motor. So in an attempt to adjust the rockers/valves I am now chasing compression(I can't seem to line the cylinders up within 15% difference of each other). Most are around 130-140psi on a cold test but I have #1 at 70 and #5 at 185, I can't raise #1 or lower #5 for some reason. I need help getting this car to run properly and it's driving me crazy!! I need good compression with zero to minimal valvetrain noise....please help!! Can you get this valvetrain sorted out??

My car has 12250 miles.
My car has a manual transmission.
