I've been quiet through this entire thread, simply because it's none of my business. I was quiet when you posted the picture of the metal shavings packed in behind your balancer bolt, I was quiet when you posted the pictures of the clearanced rocker arms, BUT, WTF is the deal with the welding/rocker stud relocation process? That workmanship looks like SHEET......

I now fully understand your position. If this work was all done at BES, that frankly is hard to believe. Something seems screwy !!!!

All of that aside, it appears as though the machined surface of the cylinder head that the rocker studs/guide plates tighten against, could use a couple of more passes on the mill. Since you're going with a rocker shaft system, changing the height of this surface in relation to the valve stem tip location can be accounted for in the engineering of the rocker shafts. If, of course there is enough material left in the cylinder head to ensure proper thread engagement for the rocker shaft base.

Good luck,

According to Tony, the heads were not heat treated after relocating the rocker studs as it would have screwed up the port work and valve job.
