Thanks but that’s not it either. A tool is only part of it, I’m talking screws and locknuts. Google “ How to adjust valves on a Ford Y Block “, you’ll see what I’m after. There’s a fellow doing a how to on a model A with a Y block.

Hi Joe, I checked that out before posting; nothing for Y blocks.

Google Summit Racing equipment, and type in valve lash adjusting tools.  They have 38 different kinds listed.  Joe-JDC

My 312 has the flat screw head and 5/8 locknut on the rocker arm. Trying to hold the screw steady while tightening the locknut is a real hassle as the screw always wants to turn just enough to throw the setting off. I wind up setting the lash wider trying to compensate for that little bit as I tighten the locknut. I saw real good video of a fellow adjusting valves on a Y-Block using just a feeler gauge and a socket style wrench, each valve took him a few seconds to set the lash. Does anyone know of this type of setup?
