Yep, not a big job. You can use the 5.7s but the 6.1s are even stronger and cost the same, pretty cheap even from the stealership.
With 240,000 on the clock anything can happen at any time, but you can totally rebuild it pretty cheap. I had a 4.7 HO in my old Grand Cherokee drop a valve seat and pretty much grenade (see Jeep Section), and bought a complete engine rebuild kit - I mean everything, pistons, rings, timing, right down to freeze plugs for under a grand. Rebuilding a OHC in the vehicle was a b*tch, your pushrod engine would be a breeze in comparison. The key was I got it shut down quick, only had a couple slight scratches in the cylinder wall on the one the seat dropped in. Scuffed out perfectly smooth.
If it was mine, I'd do a minor overhaul, replace the springs and drive it like I stole it.

What p/n is the 6.1 valve springs?
Also do you know the p/n for the seals?
Should I changed the keepers as well?

I bought just the stock springs P/N 0503 7477 AD, valve stem seals FelPro P/N SS 72914. The push rods' P/Ns 0503 7475AB-001 and 1-0503 7476AB. I bought some keepers (P/N 5301 0515 AA) just in case on of 'em went zipping off into the fourth dimension. Wound up not using any new ones. The dealer wanted $340 for new springs. I bought a full set with push rods and valve stem seals for < $200

Yep..... I bought my springs a long time ago from Art at Hensons Performance.
No need for new keepers but as Mike said above...... Always better to have a few as spares just in case.
If you do this yourself, Weedahoe has a video tutorial on how to change a camshaft on here.
You can use that for guidance on your springs instal.
Look under his signature for the link.
Its a quality walk through and time well spent by Weed, for us all to benefit from him.
Props Weed.

Well I waited to long. Broke a valve springs yesterday. Forced to drive vehicle 100 miles but made it home. She has 288457 on odometer now. Decision time. Fortunately the valve didn't drop. Summit has a set in stock of "sealed power" springs. Any thoughts on these? I could fix this weekend.
This vehicle is my job and sure would love another year of service from her.
