DIY intake manifold

I plan on making my own intake because I have 6.1 heads and an pre-eagle intake and don’t want to get the car timing cover so, I’m planning on just running a 6” pipe down the middle and welding runners, my only question is does anyone know how to make places for the injectors?

Google "fuel injector bungs aluminum".. there are a bunch of them. Machine the manifold so the injector spray is aimed at the back of the intake valve.

How important is the aiming of the injector?

Not sure, but the hot valve helps atomizes the fuel..

Another alternative would be Joe's OCP manifold.

I use an OCP intake manifold as well for my boosted 392 (5.7) stroker with 6.1 heads. It has special porting done and it performs well.

Two things though, with making my own it’ll be spec-Ed the way I want along with saving a bunch of money and no wait time

The best part about doing it yourself is you know who to blame if you don't like it...
