Ah, yes! Here we go! 1969-70 deck height is 9.480, 1971-95 deck height is 9.503. From the Ford Racing catalog. Good information to have, especially if you're rebuilding a '69 or '70. Keeps you from mashing those pistons into those valves, or worse! Would give you a surprise on the compression ratio at least!
