nuther BP head bolt question

Grant Erwin · 2005-11-03T01:45:56+00:00

A J-head is held on by 4 1/2" bolts, as many of us know very well. I am planning to work on my extra J-head, which is at the moment braced up on a rolling platform. J-heads are devilish awkward things to move, lift, or do anything with until they're properly mounted. But I have to work on this one, so I'm planning to mount it on an inexpensive engine stand, procured today for $25. First woops is it won't mount on the 4 fingers of the engine stand, they don't go that close together. So I'm going to make another mount plate, my engine stand mount plate just uses regular 1½" pipe.I'm wondering if any of you guys know the bolt pattern of these 4 bolts. I stuck a piece of steel under there and punched it using my transfer punches (there are those ubiquitous transfer punches again) but the pattern is really crooked and I figure someone knows the actual designed values. Anyone?GWE

Thanks Gunner, I'd be in your debt if you could score me a head that would work. Check this link and scroll down about halfway. There are two TM/UM's with vertical heads. Whats the big Bridgy on the left? Not that I want to try this, just curious. Tom
