So I had my '97 K1500 Suburban 5.7L/4L60E in the shop recently for an oil change. While it was in there I had my mechanic check out a couple of small engine oil leaks and the conclusion is that one of them is coming from the timing cover, and the other from one of the valve cover gaskets. All of the above are original equipment with about 150K miles on them. It's not leaking bad enough to bother me right now, but the next time it goes in for something I'd like to have the parts ready to go. Here's the list I've got picked out, all ACDelco stuff.
Timing Cover - ACDelco 93800970

Timing Cover Front Seal - ACDelco 10228655

Valve Cover Gaskets (X2) - ACDelco 10046089

My gut instinct is usually to stick to OEM ACDelco stuff when possible, but if there's anything that's a common knowledge upgrade (like the Fel-Pro Vortec intake manifold gaskets) I'd love to hear about it. If anyone has any recommendations please post them up.
