It depends. If the shop has a good reputation and maybe can show you some of the big repairs they've got going on (to prove they aren't just a bunch of lube and brake jockeys), I might. Or if someone you know can recommend a shop. There's one in the next town over from me that my dad trusts from him having to use the guy for repairs for company vehicles (me and him don't trust ANYBODY, we do 99.9% of wrenching ourselves) and that guy is a real car guy, has built several engines/vehicles over the years. Somebody like that, I would trust.
If you don't have that/can't find it, I'd try to seek out a performance shop that specializes in Mopars. They may try to turn you down for just a regular cam/lifter job but if you upgrade to, say a Texas Speed stage 1 or the new Chopocobra cam, they may agree to take it in. Also,
@Wild one is correct, there have been TONS of lifter failures the last few years. They're expensive but I would lay out the extra cash for the Johnson's for piece of mind.
