vortec valve springs ?
 i am in the process of rebuilding the 350 in my daily driver 70 stepside. i got a pair of vortec heads (062 castings) from a guy that said he had them machined for stiffer springs up tp 550" lift. the cam i have is for low end torque(207/213,437/454") wich is want i want, i rarely go over 4000 rpm. my question is, should i have the springs changed back to stock ? should i be concerned about too much seat pressure ?
