replacing head gasket and thinking about adding upgraded valve springs since the head is off and getting decked. Are there any real gains from upgrading valve springs for my truck? i do not plan to add any more power or performance parts from here on out just figured since I'm here I should do those or not. If  i should upgrade them what to and what is all do i need to order todo so?

If you run high boost and/or high RPM, then it's a good idea. If not, I think it'd be a waste of time and money. 

Yeap^^^

 

Not so much because of high boost unless you are really up there...like 80+lbs.  More so for higher rpms.  If you want to be cautious change to 115's if you are breaking 3500 rpm regularly, otherwise definitely do it if you are breaking 4000.  Not needed otherwise.  Stronger springs will put more stress on the tappets, pushrods, rocker arms and cam...and valve adjustments will need to be done more often.

 

With all that said there are many out there breaking 4000 rpms on stock 60lb springs with no issues.  I also have been between 3500-4000 rpm many times and regularly push 60+psi and I am still on stock springs with no issues. 

In my case I believe it's back pressure from exhaust brake that pushed seals off, and if it's pushing that much I went with better springs and pushrods, also with bridges to keep valves from pushing sideways and wearing guides out.
