Lq4 rockers and pushrods
I purchased these for my swap. They are Elgin Rockers 7/16 1.72. I also am installing Elgin stage 2 cam with Pac 1218 springs. I was not planning on replacing push rods as the set i have are new but factory lq4. Do I have to replace the pushrods due to the rockers I purchased or will they be ok. Not planning on ever being over 450 hp motor.

With any kind of bigger than stock cam I would go with better aftermarket push rods. Not expensive.

I'm running the "stage 1.5" cam in my LQ4, E1839P, with pac 1218 springs, and was running stock 100k+ pushrods for 15k miles, no issues. I am running stock rockers but did do the summit trunion bearing upgrade.
Did a refresh a while back and now have summit pushrods in it. Can't say I can tell a difference, but did change some other things around while I had the engine apart.
