I've used "the Right Stuff" on a grand total of three engines, so not much of a sample size but I'm happy with it. I removed one of those heads after about 5years (say 40k miles) and the seal still looked good.

I haven't bothered with JB Weld on minor pitting, I just let the Right Stuff fill them when the head is installed.

Disclaimer - I know virtually nothing (just ask my kids).
