I have a rotation of intake manifolds that I hydrodip and sell with a core charge for a return piece.
The one I'm finishing up is a ACDelco 89018222 aluminum upper. It's being dipped in carbon skulls then topped with 2000° clear. Liquid Concepts is scaling the size down to 2.5"skulls for me so it'll fit the part better

I smooth out the casting lines and get the manifold in spotless condition inside and out and media blast it, before dipping.
$175 after core, does not have to be the same part# for the core but must be same material, aluminum for aluminum an composite for composite.
