318 LA rebuild after losing a valve seat

Found TDC using a dial indicator, and #1 is sitting .077 down @ TDC. I couldn't quite figure out how to find BDC accurately.
Good work for confirming these 318 CH numbers. CR will now compute out about 0.15 lower but does not change the situation on the build. No need to find BDC unless you wanted to verify the stroke length.
