I emailed beet and they say they used stock springs.

I'm taking the cams to my builder to have them measured. I will find out how far they can grinded before I need new springs and before I start running into pistons.

I went for 13:1 J&E. If it needs it, I'm having the bowls of the combustion chamber blended to lower it slightly to 12:8. I'm getting the compression ratio measured.

Will get assemblies balanced too.
