360 LA installing Promaxx Aluminum heads

Headers? Use ether TTI, Doug’s or Hooker Super Comp headers @ 1-3/4 primary tube. The Hookers fit excellent. I have a set on my ‘73 -340 Cuda.

Id give it more cam duration and a crap ton of lift with those heads as that cam is a broom stick & unworthy in my world for those heads.

Do as you like and enjoy.
