I'm curious what you ran for valve springs and why such low C.R. .? Is it due to the iron heads and chamber design ? I assumed one could run close to 9.9 safely. Especially at 3000 ft.

Your cam card pic wouldn't open for me.....

LOVE THE STOCK LOOK!
Will need to check on the valve springs, can't recall off top of my head
