I have the stock cam from my Camaro that came in today. Was in once of my bins at my parent's place. Gonna throw that in and see how this works. gonna use a 3m pad on the lifter bore tomorrow. Was too shitty today but I cleaned the heads up... or got one cleaned up. Pulled one broken exhaust bolt out of it. Was the one head that the guy didn't take out. I think he broke two exhaust bolts and said fk this and took the cheap route.
Valve seal on one of them is loose. gonna do those now too. (they came w the top end kit I ordered.) I chased all the threads out on everything. So much better now.
No casting numbers besides these (and one more on the adjacent runner I forgot to take a pic of.)
