Hi guys.
I have a 2016 LT4 i'm lightly modding and putting in a 56' GMC. I ran into a weird issue with the Texas Speed TSP182RR-ADJ-LT1 rockers i'm installing on the heads. I backed the adjusters ALL the way out and installed them on base circle and they load the springs. I waited a full day to see if for some reason the lifters needed to bleed down a lil and they are still loaded. I'm using a stock sized 7.850-11/32 BTR pushrod.

I'm thinking about setting up a dial indicator and measuring just how far it opens the valve as I tighten it to spec

Do these arms require a smaller pushrod? And if so why doesn't TS specify this?

Thanks for any help

It sounds like you need a different length of pushrod for those rockers. Anytime you change someting in the valvetrain you should verify pushrod length.

For sure, but why are they listed as upgraded replacements for stock if you need to replace pushrods?

You make no mention of a cam change.
I understand their statement that if you replace STOCK p rods, these are suggested.
A totally different set of circumstances with the addition of a cam.
Post 2 says it clearly... Check the length.
