Bronze trunnion update... Replaced my passenger valve cover on the TA. While it was off I checked the rockers. I have Smith Bros bronze trunnions. They have about 15K on them and they were all tight.
I haven't had any issues with stock trunnions. I was just over .600" lift, 232°/236°@.050, on a 112° LSA. I also had 921 Comp dual springs with just over 400lbs on the seat because AFR shimmed them wrong. No issues. But I went with the Comp, ahem, "upgrade." Junk in 20,000 miles. So I try to stay with OEM trunnions.......

At the time my stockers had 95k on them, so I viewed it as cheap insurance. There is a weekly car cruise that another 4th gen owner attends. Last year he walked up to me and pulled a paper towel out of his pocket that had a small piece of metal in it and asked if I knew what it was. IIRC his car had 30k or so. I told him it most likely was a rocker needle bearing. That week he did the upgraded trunnions.
