I'm looking at having some rocker stand shims made in different thicknesses. These would be one piece, that would span across the entire cylinder head, supporting the end stands, locating off of the stand studs/bolts, and having holes for head fasteners.
I routinely have to make shims in .060" and .125" thicknesses, so I would offer them in those thicknesses.
Not sure on pricing as I'm still getting quotes. Obviously the larger quantity, the better the price would be.
