you have a 4k spring with no valve springs?? you are lucky not to mess up alot!Hope the move goes well Nick. Wish I lived closer, I'd give you a hand and another truck.
It's weird that I can't find any information when searching for the pound-rating of the stock vs HD exhaust valve springs.
The HD valve springs are 60# *over stock*, but it's hard to find the actual spring rates of each one. Then there are the 110# (over stock) springs that are mostly for 24valvers, but I guess some pullers use them on 12 valves. ??
Seems like it wouldn't be too hard to check if you have both laying around. I don't.
I still have stock valve springs. That should be next on my list... then I can do a valve adjustment too, which I'm sure has never been done to my truck. :doh:
