Stick with just stock cam and lifters?

(Changing oil and filter in the morning and checking for metal)
Can I ask what oil you were using?
Read the thread in my sig, different oils and additives can stop hemi tick.
Here's a dyi thread to see what is involved.
Lifters are hard to find, even ram forum vendors avoid selling them. Prices for cam swaps are all over the board, from 1800 to 7800 and beyond. And swapping ifters/cams is a risk if there is metal in the block, no good way to make sure this isn't the case, at that point you mise well replace engine. I would think under 4 grand is a fair price, if you can get a dealer under or around 4 grand I would jump on that. Call your local dealers and ask about how much for lifter/cam job. Ask for old cam and lifters, just tell them you want them for your purposes. Take pictures for ram club.
Some guys replace oem with hellcat lifters, enquire about that with dealer. If the dealer wants more then 5 grand, I'd ask every shop in town. This is such a large known issue, I bet everyone of them have done a swap. Recently we had someone with an issue after using non dealer shop, thus why I prefer a dealer first. Hopefully they don't write of the risk of metal in writing prior, if they do, you might want to think about it.
