My dad just rebuilt an A14 w/stock cam, pistons, etc. for my sister's car. However, he shaved/milled the head something like .120" (hundred and twenty thousandths)!! With a stock A12 Hitachi carb, stock exh. manifold and 2" exhaust this thing sounds really lumpy! I've never driven it, but he claims it makes as much power as his other A14 with bigger cam, stock compression, dual SU's and header. I'll have to give it a spin when I go up there in a few weeks. If compression is really worth that much in the A series I'll be mad that I've been running less than stock for so long (8.5:1), but even so low 16 sec quarter mile is impressive for stock bottom end/compression!
