Default still trying to figure out these Pan pushrods HELP PLEASE!

Doing a pan/Shov to pan resurrection. Posted a previous inquiry, and still stuck.
Talked to my ol Harley guru and he stated that I could use the solid pan rods with my existing lifters.Rods are all the same length.
Small ball to lifter big ball to rocker arm.
Go to put these in and intake lifter will not go down enough to fit these rods in. I compared the length of the rods I was using with the shovel tops, and it appears 2 of the push rods are shorter. These rods both have small balls on each end. I'm guessing it would be a bad idea to use them even though the seem to seat in the rocker arm with little to no play. On a side note the longer bigger ball rods fit in the rocker nice but are only 50-60% in the seat. Upon further inspection, the wear on the ball looks like this is how they fit. Here is a pic of both sets I have.

From what Colony sells, the rods for Pan and Shovel are the same.
My bike is a 1950
The long rods in the upper photo are from a 57 pan
mmmmmm

Longest to shortest. Front exhaust,rear exhaust,intakes. The angles from tappet to rocker arm are what makes for difference in length.

Fixed length pushrods in a Pan or Shovel is something I've never seen but I haven't yet seen everything. However same length pushrods are not going to work. And fixed length pushrods will not install without rocker removal. Pop the pans,pull the rocker arms,install pushrods,reinstall rockers. What lifters are you running?

Do yourself a favor and buy a set of adjustable pushrods. Fixed pushrods are the reason you have to remove the rockers on an EVO to replace pushrod tube o-rings. Don't see any advantage to running them on a Panhead.

Curtis,
The fixed length Panhead pushrods are used when you run the early type of adjustable lifter/tappet ('48-'52) with the adjuster built into the lifter/tappet. It's similar to the type of lifter/tappet used on the Knuckleheads, but the early Pan pushrods used with the adjustable Pan lifter/tappet were the pushrods with the hydraulic lifter built into the top of the pushrod. On my '54 Pan I run the early adjustable tappets and fixed length pushrods.
I like to refer to "tappet" or "lifter/tappet" when I'm talking about the early Pan stuff (in order to try to avoid confusion), since the "lifters" were integral with the top of the pushrod. Hope this makes sense.

A couple of other things -

The Pan rocker arms take the big ball pushrod.

Also, if you are sure you have the right length pushrods, and if you've already tightened up all of your adjustment and the lifter/tappet is bottomed out, and the pushrod still won't quite go in, you can usually very carefully pop it in by levering or prying it in. Don't go crazy doing this, but if all you lack is a little bit, it works.

Geo.

Thanks for all the info and thanks Geo
I have adjustable tappets in place and just ordered 48-52 pan solid rods , I'm hoping this works.
It doesn't make much sense to run adjustable rods, and have adjustable tappets.
I'm thinking it's either or correct?

Man it has been a long time since I saw them. Totally forgot. Never liked them 'cause they rub so bad especially if you run any kind of lift and had a habit of spitting the front exhaust 'rod out. I was thinking Sportster too but dismissed it.
