We are gonna need more info on the engine combo and target RPM range but....
We run Manton, Smith Brothers, Trend or Steward pushrods in our serious engines. Any of the technical help people at those companies can give you good advice about what you will need.
Trend makes most of the .080 wall moly black oxide units.....
These are fine in most applications......
They also make .125 wall and tapered units......but you would typically have an engine with a whole lot of spring pressure to warrant these.

My personal priority's in deciding on which pushrods are:
1. The biggest diameter pushrod I can fit in the engine.
2. The thickest pushrod tube I can get .

11-616-44 Camshaft
15854-16 Lifters
953-16 Valve spring
1732-16 Valve spring retainers

I have written with Maxwell at Comp Cams, He select suggest going with the Hi Tech 3/8 .135 wall pushrods
But I do not like the ball end. because it is made in one piece, I drove with Comp cams Hi-Tech 8680 3/8 .080 wall thickness,
three pushrod smashed the ball end.

You've posted this 3 TIMES, yet haven't answered any BASIC questions about what power level/RPM range you're trying to achieve. There is a lot of good information available here, but in order to be able to help you, we need more information to work with.....

Happened to me too, will never buy push-rods with the ball on the ends. Was checking the lash on my 406ci solid roler and it was changing all the time. Took a pushrod out and the ball on the end was wearing down, I threw them in the garbage
