Hi Folks,
I have two sets of adjustable rocker arm assemblies. I'm in the process of rebuiling and restoring both assemblies, including drilling out the valve side oiling holes. One thing I noticed between the two assemblies is the adjustment screw is a little different on both sets. One one set, the adjuster screw has a 7/16" head size, while the other assembly has a 1/2" head size for the adjusters.
As far as I can tell, the screw is otherwise exactly the same. I haven't taken apart the 1/2" assemlbly yet, but the ball that sits in the pushrods appear to be the same size for each.
Did Ford offer two different sizes or change sizes after a certain year? I don't see part numbers on the adjuster screws, so hard to tell.
Thoughts?
Cheers,
Matthew
