Athena "Big Bore Racing" - P400485100098 Measurements are minus the 1.45mm that the head protrudes into the cylinder Timings are via a calculator using a 0.3mm base gasket with 0.9mm squish, or deck height? - Might not have done this correctly though, so assume timings are not absolutely accurate. A tranfers are suprising low  |
