I have these two sets of 16 push rods from when I switched my roller lifters from Morel to Johnson. One set is 8.725" long and is marked JPW PR5-8725 From what I have researched, they are JPW Performance Components push rods. They are 4130 Chromoly, 5/16" .080 wall thickness. The other set is Trick Flow push rods, 8.900" long, that are also 4130 Chromoly, 5/16" .080 wall thickness https://www.summitracing.com/parts/tfs-21408900 I mistakenly ordered 8.900" push rods when I needed 8.950" Both sets are like new. 50.00/set + shipping.
