Hello All, I'm trying to adjust my valves and just ran into a wall. I seem to have the three wrench type tappets in this B block in an A car. With the tappet all the way up there's not much of the tappet to grab with a wrench. I can't figure how the last guy was able to adjust. I would need the tappet wrench to be about .040 thick. Is this normal? I don't think a sheet metal wrench will do the trick. In the photo the tappet on the right is all the way up. The intakes range from .013" to .017". The exhaust range from .015" to .017" Is this close enough to just call it a day? I have no idea what cam is in there. Thank you for your help!
