Here are a couple of notes for future reference: The springs I used were BBC springs, Sealed Power # VS 657. They are smaller in dia so the valve guide bosses had to be machined & the shop charged me $120 for that. The smaller spring required new retainers and that part was Comp Cams # 744-16.
The benefits are stronger and easy to source springs and hardened retainers. From vendors, new springs & factory keepers seemed to be a little more than $200 and my cost here was around $240.
