Snap on sells a torque adaptor. I have one works great! I think it was 25 bucks.

Torque is 55-75 ft-lbs.  I found with a bar type torque wrench (has a small head) and a socket that I ground down to be able to get to the two bolts by the exhaust ports (that are blocked because the cylinder stud is directly underneath) I'm able to get to all the bolts w/o an adapter.  Never had any luck w/ those adapters, especially reaching the rear cyl left side rear head bolt that's closest to the coil.

Ignoring that doubled up crows foot, I use the rest of this pile-o-stuff (and some figuring) to get to the head bolts.

55-75 ft lbs.I use a ground down box wrench & just tighten them all as tight as i can & then give the end of the wrench a few good smacks with a deadblow hammer.Been using that method for 16 yrs now,have'nt blown a gasket yet,probably just lucky!Just tighten up a little at a time,& be sure to re-torque

Mark, I know how difficult it is to get a torque wrench in there, but extending the lever gives an inaccurate torque value. We need to keep it as short as is humanly possible. The SnapOn adaptor is awesome.

I cut two combo wrenches in half and welded them back with a box on either end. Same principle as yours.

Don't have the formula here but isn't it just in the math?

Also as long as the wrench is 90 degrees from the extension I was told the torque setting is correct or very close to it.  I could be wrong but that's how I use it so far..

 Rudy, long as you keep the adapter, etc at a 90 degree angle to the torque wrench the torque value will still be the same.  :up: On my Panhead I use a dog bone adapter from McMaster Carr that looks alot like the one in Mark's picture.

Here's a link to a torque calculator  so's y'all can do the math yerself.  http://www.cncexpo.com/TorqueAdapter.aspx

I think that torque adapter is the only snap-on tool I have.
The obstruction wrench is proto and I had to sand a little off the OD of the box end to be able to get it in there. The socket head driver is from NAPA and the torque wrench is Craftsman.

any port in a storm
