Funny little update, I just went through all of the pull-off rocker ams to check them out. There was one random self-aligning rocker arm mixed in with all of the other flat-bottom rocker arms.
Also, the LT1 cam turned out to be too damaged to reuse. I guess that means I'm in the market for something comparable, because a stock spec '93 LT1 camshaft is at least $360.
Also also, because I'm an idiot, I'm set up to meet another guy for some 906 Vortec heads this weekend. My instincts tell me, based on how cursed everything else has been so far, at best one head will be bad and one will be good. Then I'll be stuck with an 062 head and a 906 head, and no one anywhere near me with a good match for either one lol
