hi darrel ,,, yes i agree but i want something to be a good fit on the new shafts and used ones will be sloppy.i have tried macs and they make new arms with adjusters but of course there are none on the shelf and do not know when new  stock will be made.i have toyed with  the idea of using old arms and machine out the bore a few thou and inserting bronze sleeves,,but this is still in the thinking stage..thanks form your input..(yes that oil will be changed!)

I used these guys when I rebuilt the top end on my '55 Merc engine. Great work and and quick turn around.

wouldnt the old screw with lock nut work on your rockers.without changing them.im talking about the early ford rockers

Those rockers will work, get 1956 or older adjusters (lock nut type), use factory Ford push rods, do not buy aftermarket rocker parts there all made in the same place, you may want to use Ford Fe or inline six adjusters (non lock nut) yes they will work.

PS Do not use blue head gaskets (water leaks down the sides of the block)

thanks dobie,,, lets not forget that i live in oz

yes that is a very likely thing that i may have to do,, thanks for the input

are you suggesting i throw my pushrods and use the old style solid rod??

Oops! I forgot about that.

Best I remember, in Australia the Ford Falcon 144, 170, and 200 (early) all used the same push rods and rocker adjusters that a Y Block Ford used, use the tubular push rods not solid, you can use the adjuster screws from a 223/215 Ford 6 also.

i cliff,,, yes i am using tubular pushrods not the old solid but i do notice the cup shape at the rocker end seems to be slightly different to the original idea and hope this did not add to the problem.what is your opinion on that particular type rod i have used?? any thoughts or experience? we are checking out the falcon adjusters.
