This issue of head gasket thickness has puzzled me for some time. I
understand why this was such a big issue in the old days, because people
used off the shelf pistons. However, now if you're racing a TR3 or TR4
and want 87mm forged pistons you probably have to order them custom made
from someplace like Wiseco. Why not order them with a greater
compression height to make up for the thicker head gasket? I believe
2.00 inches puts the top of the piston at the top of the liner. If
you're head gasket is 0.045, you could order a 2.10 compression height
for an 0.035 clearance. This is pushing the limit, so you'd have to be
sure you've got all the correct dimensions. Am I missing something?
