I used a 1/4" thk 16" square steel plate with a 4-1/2" hole bored in it, the hold down bolts are on a 5" square bolt pattern. The "standard" is a 5" hole with the hold-down holes on the 5" square.
To clarify this would be the top of my bench and not the cylinder head adaptor. The head/carb, part to be tested adaptor could be made from almost anything depending on what you are testing, I have used alum, steel, pvc, clear acrylic and wood for my testing already.
