The machine shop set the valves cold good enough to go. Told me to make sure I adjusted them hot. When would you adjust them, asap or after a couple of hours of run time or even longer.

After a couple hundred miles re-torque the head and check the valves again. | | | | | Joined: Mar 2002 Posts: 9,115 'Bolter | | 'Bolter Joined: Mar 2002 Posts: 9,115 | The step I missed was not re-torquing the head before adjusting the valves, after the first run. I found the torque values on the head bolts were way down from when I did the build. The manual advises to re-torque the head. | | | | | Joined: Feb 2004 Posts: 29,886 Kettle Custodian (pot stirrer) | | Kettle Custodian (pot stirrer) Joined: Feb 2004 Posts: 29,886 | All head gaskets take a little "set" when they warm up, even the supposed "no-retorque" types. On something as easy to reach as a stovebolt engine, I choose to re-check the head bolt torque after the first warm-up, then tweak the valve adjustments if necessary. The valve cover has to come off anyway.

I thought I remembered this as the stumbling point in the 'easy to reach' scenario. Maybe a crows foot wrench would do it, but I don't think that will work either.
So a head retorque requires you to remove the rocker assembly, yes or no?

It's not all that difficult to make one out of scrap metal with a little creative welding, though. Otherwise, I guess pulling the rockershaft is the only other option.

There are two inner bolts on mine that I use a socket with a universal on it. These are as you say near the center of the head. For the front most one, I remove the next rocker shaft bolt, undue the valve adjuster, slide the rocker forward out of the way and then torque the head. | | | | | Joined: May 2006 Posts: 8,351 'Bolter | | 'Bolter Joined: May 2006 Posts: 8,351 | Don't forget to check the torque on the rocker shaft assembly mounting bolts before you adjust as well. It will make a difference.
I don't recall having to take the rocker assembly off to torque my head bolts either. IIRC, my socket was just the right hight to clear it, it's a Mac 3/4 thinwall semi-deep impact socket, and I was using a Snap-On torque wrench.

My head is a 1951 and that probably makes a difference. | | | | | Joined: May 2006 Posts: 8,351 'Bolter | | 'Bolter Joined: May 2006 Posts: 8,351 | That's probably it. Been a while since I've messed with a 216 or early 235.
