Check that your shim is seated well, there should be no problems then. What's the size of the shim?

The shim is seated well and the size is 1.84. I put the bucket on without the shim and still didn't fit.

When you install the exhaust camshaft, piston at TDC what's the clearance? Can you take a picture?

No it's not at tdc. I can't move it right now because the valve cover and cams are off. Is there another way to move it? I can't upload a pic right now.
