Steve Morris Rocker Arm Trunion kit.
https://www.stevemorrisengines.com/s...d-service.html
I've read about failures caused by this issue, my car seems to have all of the common issues so I figure I better head this one off. I've also read of the kit with needle bearings being unreliable. How about the kit linked above? Car is down for other (a lot of) repairs so I want to get this out of the way.
I have a small press (2-ton I think), will that be sufficient to press the bushings in/out?

The kit without the bolts is 159.00 also

on the Morris kit, the trunnion has a couple grooves for oiling, don't know if the Straub does, they might i think it's a upgrade over the original bushing style kits.

I installed these with a bench vice. I used the summit trunnion install tools and it was ridiculously easy to do.

Though, I'm not sure it's really necessary if you're running a stock cam. Issues really start to come into play with higher lift cams.

I got the Straub kit yesterday. Hopefully will press them in this weekend. Will be another week before installing back into the car.
There is more clearance between the trunnion and bushing than the roller bearing trunnions. The brass bushings can rock slightly on the trunnions. My roller bearing type had zero play even with the trunnion worn out.

The stock bolts have a larger shaft diameter near the bolt head, the old trunnions have a larger hole hear the top to accept them but the new trunnions don't, the old bolts will bind on the new trunnions near the bolt head. These won't bind because they don't have the larger diameter near the bolt head, https://www.mcmaster.com/#91290a448/=16i10di.

And you don't really need a 2 ton press to install these bushings. I have a small, bench mounted, hand powered, Arbor press, and it worked just fine. This isn't a "brute force" job, it's a finesse job.
