On previous installments of valve springs I have used single springs but this last time because of the cam, we use dual. On single valve spring installment we pre-assembled with the valve and valve guide bushings and slip them into the valve guide bushing bosses. On the dual valve springs, this cannot be done because they are larger than the valve guide bushing bosses.Do we just place them in the valve lifter gallery and assemble them there with the valves?
