Valve Springs

Okay, need to replace the valve springs on the truck. My question is has Dodge made improvements to the factory springs or is after market the way to go? Am planning on replacing all the springs not just the one that collapsed. Is that the right thinking?
Thanks

Yes.
6.1 ex. springs if cost is a factor, Manleys if it is not.

Super jay thanks for your help and patience thru all these questions.
Does 3rd strike have these?
And is it easier to use compressed air or remove the heads to do this?
Where can i find the part number for 6.1 exhaust springs?

I personally prefer the 6.1's over the manleys even if cost wasn't a factor.

It'll definatly be easier to pull the heads to change to the 6.1 springs. With the spring cups that come on the 6.1's it would be really hard to get a compressor on them. IF you pull the heads you'll also need to get a new set of head gaskets and head bolts.

Okay, thanks.
So the head bolts are torque to yield.
I was reading another post about shims and .060
taken off. I am not the fastest or brightest person to join. I could not keep up the the post what was being said?

I've read both ways, some people say the bolts are TTY, and some say they're not, so I took the safe route and replaced them while I was in there. Definately replace the MLS gasket though. You won't need to shim the 6.1's if you leave the cups on there, if you take them off I think your right that you'll need to shim them .060" to get the correct pressure at the instaleld height of 1.81". I think that's the right installed height anyway?? jay will know for sure.

Hey gary. How many miles are on your rig? I was thinking of replacing my springs. Are you going to do it yourself? Let me know how it goes. Thanx.

These are a cool way to adjust spring heights on Ford, and Chevy motors. Not available for our Hemi yet. Notice hoe the groove is placed different to allow different heights.

Hey gary. Sorry to bother you again but I have a couple of more questions. Does your vin # in your truck start with a 1 or 3? And did the valve drop into the piston when the spring went?
