So I am beginning my GT40P head install next week, and I have an E303 cam and the last thing I have to do is order valve springs. I've been entertaining two choices; the alexsparts spring upgrade and the crane beehive springs. I like the idea of saving $80 on the alexsparts springs but while I'm in there, is it worth the extra money to go ahead and get the crane beehive springs?
