FL head type rocker arm and push rods

Will these fit on a 55 Major, they are a heavier push rod and the rockers are in nice shape... thinking about swapping the setup for my 55's
 

Look like they would but all the FL valves have caps on them and the Major only on half the valves, could be a problem, push rods seem the same length but a little more skookum.
 
The FL head will fit but there is a problem. The valve springs were far
stronger than the Major and the FL tractors had uprated cam followers, cam
shaft with a single bolt fixing, timing gears as well as the rockers. Even
with all the upgrades Supers with FL heads would eat cam followers and cam
shafts back in the day. Our dealership changed a lot on relatively new
tractors.

One of the first questions I answered on this board twenty years ago was to
identify "rings" found in a Super Major 5000 sump. They were from cam
followers where the centre had been worn out. I got a new set and a new
camshaft and sent over to the US and it was not cheap.

I would stick with what you have.
 

Thanks for your reply but yes, I read up on the head and that is why I didn't use it, I only wanted to use the rocker arm assembly and push rods if they would work.- Kinda like my old Harley, if there is something that is a better upgrade than the original, well you know:)
 
Mine is a 55 Major, but for an hours work if that I can check it out...mine are a little worn and these ones are in great shape so it's worth the time, all rebuilt with very few hours on it and now to put it to work, thanks once again for your input, kind of new here and this site is a great help......
