Headbolt heater removal?

My 67 250 6 cylinder has a Freeman head bolt engine heater installed, that I would like to remove.

I assume it was put in by removing 1 bolt and installing the heater. Would I be ok removing it and replacing it with a head bolt as long as I torqued it ?

Yes interesting, would like to see what they did to pass thru the valve cover. I've heard of the heated oil dip stick, but not a head bolt.

I always wondered why my father in law called block heaters head bolt heaters. He grew up in a small town just west of grandforks ND around the time these would have been popular. I’ve never seen one but it’d be cool to have one.

That link I posted to its history only shows a flathead engine application. It would be interesting to see how it was done on an OHV engine with all the head bolts inside the valve cover.
