Intake Manifold Recommendation




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.

Look around for a set of 5.2 heads and cam cheap and use them if you are on a budget, .397" lift vs .439" for 5.2 which has larger 1.92" intake instead of 1.86" intake of 5.9.
Cam is a roller so dont sweat new lifters. Get new freeze plugs, roller timing set and water pump, good to go super budget sleeper 300 hp would be fair est . EQ's. .500"-.525" cam and air gap should put you in the 375-400 hp range with proper tuning.
