1 step forward, 2 back. I bought those SM heads complete so I didn't have to mess around with the springs. Wish I would have thought about it when ordering the cam. Wonder if SM has specs for the heads I have...
Hold your horses bud, let’s do some checking before you spend any more money. Compare the Speedmaster spring specs to whatever Lunati recommends for that cam. I have a feeling you’ll be able to use the ones you have.
