What Cup Push Rod

Hello Folks

It is a 1985 Roller Block with stock lifter.
302 heads
Comp Camshaft XR268HR-10 Hydraulic Roller
273 Adjustable Rocker

I've seen this set up somewhere but could find it.
I'm looking for cup push rod with appropriate length that would go with this set up.
Please advice with link if possible.



Thanks
Scamp
