**** yeah its a good idea, i did a Cam on my car with 138K miles, it now has 140K and still runs good, dont forget the Ported LS6 oil pump. Good luck and keep us updated, im looking for some heads right now.

Depends on your planned uses and goals. If gas mileage is a concern I would say it is a bad idea. Obviously you aren't wanting to do that though because performance and good mileage are like mixing oil and water. Tough to have both. Sure it is a good idea. Do your research as far as heads and cam combos though. That is the main thing.

The question to ask yourself is, if and when the bottom end goes, will you be replacing with stock cubes or a bigger bottom end? That should help you pick a good head/cam combo that you can transfer over to the new block...or help you decide whether you want to do it now or wait for a new bottom end.

Well thats exactly my point. He might want to wait until he knows what hes gonna do about a bottom end. I wouldnt run the same combo either on a 346 vs a 408. But he could go with a good size set of heads and cam that might work well on a forged 347 as well as his stock 346. It all depends on what he plans to do in the future.
