Economical replacement rocker arm set?

Took the lifter out. The base looks as it should. Swirl marks and convex. Internals look fine. No real dirt in there other than the oil. The side of the lifter does have a gash which I think is from manufacturing.

I rolled all the pushrods on a glass weight scale. I'm not 100% sure the glass of the scale is true but all the pushrods seemed to have just a tiny "curve" to them. I could see the ends touch and then barely lift off the surface as I rolled them. They seemed to all have he same amount of "curve" so this leads me to believe that my surface wasn't 100% true.

So my next step is to clean the lifter with minieral spirits, check the cam lobe for proper wear then reassemble.

If the ticking doesn't go away then I am going to switch the rockers around and try again.

Thoughts?
