well man the best way to do it would be to put 4gsk and 60 lbs valve springs in all at once it cost u just as much to do a 3gsk as a 4gsk so u should do it at once imho

370s are 5X12s

Make sure you get correct spray injectors 145* not 155* the marine nozzels dont spray in the bowl create heat and smoke as well as bad MPG. You can get corect spray 5X12s for just about the same price as marine 370s.
