Hey guys,
We are changing up things with my set-up and running into an issue.
Currently have the 96 explorer motor with the GT40 heads and TFS1 cam...
Well I got a set of AFR 165 heads (part 1472) and the shop I bought them from (East PA Foxbody) gave them to me with stud mounts installed and Harland Sharp rockers. He also gave me trick flow hardened pushrods 6.15" .080.
I also have a set of comp cams hardened rods stock length.
We already installed a TFS 2 cam as well.
When we tighten down the rockers with the push rod in place, the round part at the bottom of the rocker rubs against the bottom of the stud mount. We even took it over to a machine shop nearby as well to get his opinion, he said that they should not being doing this.
So if we hand crank the motor with the rocker tightened down, it won't turn all the way, but if we back the rocker bolt back a bit it will turn. We realized this as we were doing a clay test to determine we had enough piston valve clearance.
So not sure if we have the wrong bolt with the rocker. Called the guy I got the heads from and he said to get poly locks... Not sure if this is the answer or is something else going on? Is there something that the rocker sits on between the bottom of the rocker and the stud?
Here are a couple photos:
