Hey!
I wanted to pick your guys brain to see what you guys think about this question in regards to the rockers.
First, I have a 327 stroker in an '89 mustang GT with GT-40X heads and the Ford X-cam. I also have the FMS pedestal mount rockers. My problem is, is when setting with shims I'll tighten the bolt up till I get to zero lash, I torque the rocker bolts to 20 ft. lbs. which takes about half a turn. While tightening the rocker slightly pushes in on the valve. I am at the base circle of the cam. Do I need to shim further? I'm up to .090 already with the FMS shim kit otherwise the rocker opens the valve. I am using the stock length push rods. What do you think?? Thanks!
