Intake Manifold Recommendation

Intake wont matter if you dont change the cam and heads. The 5.9 has a little cam and intake valves that will limit power much more than any manifold. If you are going to swap the heads, then get a set of "LA" bolt pattern heads and you can run any LA manifold you can find for cheap.


While I understand there is a lot of power left on the table with the stock cam and also I understand there is problems with the factory heads cracking.
But I am trying to keep this swap as simple as possible. Power wise , I will have a major increase. I currently have a 3.9 v6 125hp and 195tq.
As I progress with this swap, and if I find on my donor motor that the heads are cracked, then I would probably get the EQ heads, maybe a little more cam, and consider the LA style intake.
But again, how well will all of this mate up to the magnum accessories?
Oh, edit to add, the intake is necessary as I want to keep the truck carbed and not try to go FI.
