I think a dial indicator extension would be tough.

I've done this a lot on snowmobiles, but admit I've never tried it on a flathead Ford.

Bruce, could you explain how that dial indicator set up would work?
You are correct, my bad. You know Chrysler industrial engines had a hole thru the head for that very purpose. Just remove the pipe plug and drop in a welding rod or whatever.
