I am building a 512 stroker with trick flow 240 heads. I am aware of the specific redesigned trickflow specific rocker arms harland sharp makes, but...backordered. i am trying to get the car buttoned up in the next 2 weeks.

Are there any other rocker arms that work good with this setup? The pattern ia definately off to the side more than I like, but I may just have to run them if I cant find anything quick enough. Has anyone else found another option other than the specific trickflow rockers by Hs?

I seem to remember someone saying Comp and Hughes rockers work ok.

Crane Gold rockers if you find a set.

It wouldn’t bother me a bit to run this-

I tested a bunch of rocker arms on TF240 heads when they first came out. https://www.motortrend.com/articles/trying-find-extra-power-rocker-arm-testing/
I don't see a big problem with what you show in the picture. Use a felt pen to color the end of the valve and then push it thru a couple of cycles and see what the wear pattern looks like. It will probably look okay.
