L24 73 fly-cut pistons on L24 rods come out of the block by .030 inch. Does anyone know why the 73 pistons do this......why are they different from the 70,71 and 72 flat-tops as far as deck clearance? Is it OK to install these pistons with the early L24 heads without shaving the pistons since with the .030 positive deck clearance and the .060 gasket crush only gives you a .030 inch clearance.
