Looking at the the great info on this thread, with a stock block, pistons and Ford head gasket (.027" or 0.6858mm), if I have .020 taken off the head the compression ratio will be about 10:3:1, right?
Well, I went with .020" off and will report here how the compression ratio ended up - as measured dynamically.
