Yes they would be screwed into the water jacket.

Actually i think they may be a push fit into the water jacket and a clamp (not shown on your picture) presses down on them to keep them in place.

Well, this engine doesn't have the clamp if it ever had one. And I'm not sure how it would attach?

Hello all
To be honest I haven't seen that setup on a J before. Anymore pictures of the engine and makers tag?
Usually blind head J's and L's have 2 cast iron flange looking things held down with 2 bolts for each flange. One flange having the spark plug screwed into it as far as I knew.
Very interesting.

Cheers Scott

The "H" valve caps were similar at one time and because of their smaller size were retained by a strap held by one stud only instead of two.
