In the past, those numbers would be good at zero lash or a slight preload as with a hydraulic lifter.
They are usually a bit shorter when lash is introduced so, be aware.
Off the shelf pushrods are usually sold in .050" length differences. I can get you any size you want from Trend; off the shelf is today but, customs are a week or more to get done.

on the head with .026 lash installed. Jon Kaase told me to set the flat part of rocker parralel to retainer and take measurement as well as ck how the roller tip contacts valve. So that is what I got with this camshaft profile and adjustable pushrod checker. At half lift the pushrod is square to rocker.

Tip...... You should to order them thru someone who knows what to get. Pushrods aren't just pushrods, you need to know what materials, thickness, tips, oil holes, ect to order.

Yes get the 3/8 but make sure you have 3/8 guide plates on the heads

Trend has pushrods in .025" increments.

In most common sizes however, not "off the shelf" with all sizes.

Whatever........3/8" that is the case.
