all 6bbls had the street hemi spring; whether yellow or green stripe.
I think we've shown with the part numbers that this is incorrect.
apply some logic. why would you need a low taper cam if you didn't have big springs?
What logic would that be? In 1969 the 6bbl had it's own unique part number valve spring. The Hemi in 1969 used a different part number valve spring.
In 1970 the Hemi started using the same part number as the 1969/70/71 6bbl spring.
Reality states the Hemi started using the 6bbl valve spring in 1970 and that the 6bbl NEVER used the Hemi spring.
