Freshening Up the Motor Just curious with 160k on the clock for my motor what would be some good things to go ahead and replace kinda as preventative maintenance at this stage in the game. New timing chain? if so single or double roller? valve springs? etc...fwiw...emissions has been deleted, fuel pump is a few years old, filter has about 5k miles on it, opti was changed 1.5 years ago, i have an ewp on it, and changed wires and plugs when i did headers about a year ago. I'm also gonna be changing the intake manifold gasket again since it's leaking down the back of my motor

Stock valve springs suck new, with 160k on the clock they're costing you some hp. So I'd def replace those along with the valve stem seals while you're in there. Swapping the timing chain would also be a good idea, a stock GM replacement would be fine or you could switch to a roller since you have an ewp.
But like mentioned above, its a good bit of work and gaskets to change these things out so if you're thinking of a cam just do it now.
