I would have used straight edge if I had thought to document the deck height before I slapped the heads on. But if I do remove the driver head, I would def measure it with dial indicator to get a very accurate number for everyone. I have pass side head torqued and valve train just set in place, I was gonna torque driver side and try to button her up today, then I can finish up engine and engine bay paint. We will see what happens when I get my but out to the garage.
