I have a 1 bbl intake that I'm installing with Headers. It's casting # 3998149.
Do I need to plate the bottom of the intake? I'm wondering if there was an EGR bleed orifice on these manifolds...?

Since the intake's bottom is closed, I don't see the need for a plate unless you want to setup some kind of manifold heat contraption.

Does anybody make a heating plate for this intake, or is it time to get creative?

I suggest doing a thread search using "intake manifold heat" or other such terms. I have no personal experience with heating an intake. I do remember seeing quite a few past discussions on the subject.

I searched to no avail. My Furnace won't handle iron, but I suppose I could cast an aluminum part. That'll keep me off the streets for a couple nights, and amuse the neighbors.  CJ | | |
