Note: When replacing the engine block, rods, crankshaft, and especially pistons it is imperative to measure piston protrusion at TDC above the block deck in order to select the correct head gasket thickness. Projection MUST fall between .91mm and 1.20mm & have the appropriate head gasket thickness to achieve the correct compression ratio.
