1954 Ford 850 Tractor w/blown Head Gasket (at the very least)

Those valve caps should be an over the counter item for peanuts. Loads of engines use then and valve stem diameters fall in a narrow range so the choice should be wide. Fordson Major, Power Major, and Super Major all use them and spares are widely available.
PekkaNF:
I have a question: How much in total you skim off and do you need anew thicker gasket? Once we read on old tractor shop manual and it had a chart and sparepart numbers, tabulated on "deck height" or whatever it was that describes the "loss".

Hi Pekka, I took off a total of .014". I think that will be okay because on an old tractor there aren't many fixed parts that also attach to the head whose dimensions would no longer work. Also I'll know when it comes time to adjust the valve clearance if there's a problem.
Of course the head was already low in the center by .012" and may have been bent down by the head bolts.
So, anyway, I think there's a good chance that there won't be mechanical interference problems. A little more compression maybe. But I'm hoping the additional two cylinders firing I get out of it will be an improvement, no matter what the problems!
vtsteam:
Andrew I'll try to find those then.
A check on the internet earlier showed only the whole lvalve keeper assy - for about $30 plus $20 shipping. Damned if I'm going to spend $50 for a simple part the size of an unthreaded nut!
mattinker:
Is it the hardened little cap that sits on top of the valve? Dead easy to make! A bit of tool steel "reclaimed" annealed from an old chisel or something! Tempered dark straw at a guess. That way your sure to find the one you lost!
