Broken Rocker arm in 3.1 what will fit?

I had some upper engine noise that started after I pulled the Camaro out to get ready for summer. 3.1v6

Pulled the valve covers

Number 1 intake rocker had made a perfect hole in it's self on the spring side of the rocker arm and was loose as well.

pushrod is nice and straight and the spring looks undamaged as well

I have a set of 97 lt1 heads with all the valve train in good order

can I pull a rocker of the LT1 ? or do I need to go digging in the local pullaparts lot?

thanks for any help team

Does not look like those will cross. Seems to be a V6 specific part number. They are super cheap though. Inspect the others and replace any that show wear. Had a rocker blow out on my truck's 350 a few years ago - not rhyme or reason to it. Just happens sometimes:
