OK I'm not sure this is really a bolt-on but it's not hyper technical either. So here's the deal, I have a 1g big port head, and sent it off to a shop back in early 2019, for them to check it out and assemble it. It has GSC 280 cams, 2g hydraulic lifters, GSC beehive springs and retainers, GSC +1 mm valves, basically everything in the head is new.
Anyway The head has sat for about a year, until I finally cranked the car this weekend. I heard a noise, stopped, and tried to turn the engine by hand, and it was stuck.
Pulled the cam cover, saw that 2 of the rockers on the exhaust side had fallen out? Then noticed all of them were loose on that side! I could pull them out by hand. The intake side was firm, and had an invisible amount of lash.
I did not bleed the lifters, but after sitting a year (They were still covered in assembly lube) I didn't think they'd need it. Wouldn't bleeding them make the problem worse anyway?
Pictures always help right?
