Just another mention, but check out Durabond cam bearings, they are wider. I dunno why GM did what they did, maybe a slight uptick in mpg due to less drag, or trying to find a balance between a cheap timing chain, and longevity, but they are just so narrow, and don't even cover all of the machined surfaces of the block, or cam. Lot easier to wipe them out

If that thing is going to a machine shop, I wouldn't even touch the pistons. Not worth the solvent bath. Tighten the caps up, and send them with the block for its bath. They'll be a lot cleaner.

Thanks for the tip on the durabonds. Did a bit of reading, and there is definitely bearing differences between the generations especially when it came to ones with VVT.
And ya, I'll see what happens, couldn't cost too much more to toss some pistons in the shower too. If I decide to send it.

Fighting with buddy via text right now who wants me to put it back together with new bearings, but old cam until it's turbo time. It's frustrating!! Lol

If it's this far apart, it's not going back together with old cam, if that delays the swap, so be it. It's not going back together with old ****, and old engine isn't coming out until this one has EVERYTHING ready to go. I'm drawing the line!! Lol

I agree so the cam swap now. Also add a bung into the oil pan so you can drain the oil into the pan from the turbo. Plug it off and then when it’s turbo time it’s easy. Same for the cam, it’s a total pain doing a cam swap in the truck vs now. Look into some ARP header/manifold bolts as well, that way your not dealing with breaking bolts when it’s turbo time.
