oily mitts should be qualifying in the top 10 on the grid
Piston to bore clearance

Looking at my engine and have found I have a nearly 5 thou clearance between bore and piston. This gives me a 17 thou ring gap on the top ring. The bore itself is pretty much as from the shop at 3.190 .

What is standard practice as the engine man thinks about 2 thou clearance on the piston/bore clearance is better, with a 12 thou ring gap.
