I have a new muff and liner, and need to provide instructions to the machine shop. What interference fit for fitting the liner to the muff? What clearance for my Kemp low expansion pistons, considering the So Cal climate, 2 - 4 thou? What is the target height for the muff, from bottom face to top (deck height?)? To minimize/eliminate lapping the cyl head, I've heard of machining the lip on the liner, the notch in the cylinder head, and/or the top surface of the muff, to provide a slight clearance between the muff and cylinder head, for the area where you would use the coarse lapping compound. How many thou?
