Valve springs for my build?!
So i hve a eps .647 lift cam on both intake and exhaust. I keep reading that yella terras that i have have been failing alot lately when open spring pressure is above 400 lbs. right now i have prc .675 springs which is well above the 400lbs open pressure. What springs are out there that are good? I figure springs would be a cheaper option then a new set of roller rockers bc theres no better option out there unless im going to spend a grand on jesels

PAC springs are sold under a lot of different names too, it isn't like there are 20 valvespring manufacturers, there are VERY few making the springs for all the brands.
Far as selecting springs, you need to know the lobes, what the valves are as it pertains to their weight and the anticipated rpm you will turn it, then talk to a professional. My choice would be the cam company or the head company.
