I found some scoring at the rocker's pushrod cup and pushrod tip. The bottom of the pushrod that goes to the lifter is in good condition though. No other scoring on any other rockers or pushrods.

My motor is a 2005 6.0 lq4, what year lq4 would have an exact replacement rocker arm?

should be the same for ls1 from 97+, all the 4.8, all the 5.3, and all the 6.0

if you get into some of the really new 2010 and up stuff they might not (I'm not familiar with them), but the older stuff should be the same

most ls parts are very generic between years and engine size, unless there is an obvious visible difference

Ok that is good to hear thanks.

I thought there was a bearing upgrade early 2000s? Meaning the 2005 would have better stock bearings than most of the true ls1s and early truck stuff. Of course that means nothing if doing aftermarket bearings.

Possible, but the parts should still interchange unless I'm mistaken.

Either way if OP is switching them a trunion upgrade kit from Brian Tooley Racing is wise to replace the stock bearings anyway.

Which brings me to another point, careful listening to the ls1 crowd as then truck engines came stock with year to year incremental upgrades the LS1s either didn't get or only got the last year or two. The trunnion bearing issue was over by 2005, if stock stock should be fine, if a bigger cam then aftermarket trunnion might be worthwhile.
They will tell you to get an LS6 oil pump and later timing chain too but look into what is stock first .
A 2005 motor has a lot of lessons learned compared to the say 97-00 motors.

How bad is this from the pictures? Is it normal to see a few pushrods/rockers wear like this or does this mean my lifters are the issue?
