Marshy, i always replace my valve springs with a new cam. they "wear" in with the pattern cam you use over time. the risk of breaking one with a higher lift camshaft is a very serious gamble. plus that gives me the chance to pull the rotors off the exhaust valves and replace the valve guide seals. this is my prefered cam made by Comp-Cams. its an extreme off road 4x4 cam. dont let the word "extreme" scare you. this is what most people refer to as an "RV" cam. it has a mild lope to it at idle and sound nice all the way up to 6000 RPM. works well with a stock trans even though they recommend a higher stall converter

If you decide to use the stock valve springs then i would stay under .450" lift which this cam would be a better fit. same 4x4 style but more stock friendly

Or maybe this one which is between the other two but borders on needing new springs
