Default Cam in higher mileage L76?

I'm planning on doing a livernois stage 1 cam/dod delete over winter but a little concerned cause I have 120k on the car. I currently have good oil pressure. Don't burn any oil. No leaks. Occasionally a couple seconds of lifter tick on cold mornings but I'm sure that's just the dod lifters. IMO it's a very healthy engine and don't think it will be a problem but just wondering how many people have done higher mileage LS cam swaps.

You are just fine. Besides, all the parts that could fail, you are replacing with new, high performance parts anyways. Just do it and enjoy the results

^^^^ this is a great time to do a cam swap. Nothing like taking the heads off, checking everything out, putting nice parts back in, then driving it for another 100k miles problem free.

I would install light weight LS3 intake valves and new valves seals.

Those are the type of responses i was hoping for. I am defiantly planing on putting in new valve guide seals and at least getting the heads resurfaced and a valve job. was considering getting heads ported, milled, and different valves but wasn't sure it was all that necessarily. I'd like to hit 410-440 whp range after the cam and headers are done. But more importantly i'd like to be running mid 12's. I'd go with a bigger cam but can't afford to do headers, cam, stall, tune, etc... all at once. and the livernois stage 1 cam seams to be pretty good set up with supporting mods.
