Thanks for the responses, it turned out I had dunked Up threads in the Heads which I had mistaken for incorrect thread pitch. Chased the threads and plugs are now Installed. Thanks again

Regardless of the engine you have, you should be able to find spark plugs that will fit from Van Pelt.

Which engine does your 1937 Flathead have? The 60 HP engine takes a 14 mm spark plug. Champion H10 was installed at the factory. The 95 HP 21 stud V-8 engine takes an 18 mm spark plug. Champion 7 two piece spark plugs were installed at the factory. Later replacement one piece Champion 7 spark plugs were used as service replacements.

I have been told that my motor Takes a 18mm diameter spark plug which appears to be correct. The problem I am having is the pitch measurement on plugs appears To be 1.5, but my head appears To Need a finer thread 1.25 pitch. Does anyone have any similar issues with what I am describing? Does anyone know where IMay be able to find a plug that would fit? Is there any other solution that I may be overlooking? Thanks for Any help.
