Are all rocker arm bodies the same ( exc. rec port )? I have a trunnion kit coming from BTR, but I have 3 separate sets of LS rockers for cathedral port applications and I was curious if there were any strength/longevity differences between the years. I have my original LS1 rockers, a set from an '04 LQ4, and a set from the LH6 I'm building. If there's no difference, I'm just going to use the ones with the least wear on the pushrod cup and tip.

All the same part number. 10214664
If you ever want to compare parts between the various LS engines, type in “nemigaparts LS1”
in google and select on of the links. Or nemigaparts LH6” It will bring you to a page that has an engine diagram for the engine in question. Then you can modify the end of the URL to get to all the diagrams for the vehicle in question that contains that engine. Usually there are 5 diagrams per engine. Rocker arms are usually under “part 2”. So for the diagrams that contain rockers for LS1, LH6, and LQ4 the links would be below. Need to verify the year on the LQ4 diagram is same for 04 as it’s an 05 diagram. Sometimes the year is not correct and you have to do another search. but this is easier than searching by make a model on that site because some of the makes are not easy to find. I made an excel file that contains all the engine parts for the commonly searched LS platforms but still have more to add. Once it’s ready, I’ll upload it on here. I don’t have all the part differences memorized like some of the guys do on here that do it for a living, so this is what helped me get things sorted.
