5.4L 2V Intake Manifold (2001)

I do know if I go with an aftermarket manifold that my Ford gaskets won't work
I did some more searching and you can get the aluminum upper and lower manifolds from a 99 --- this will pretty much triple the cost of the manifold though over a new plastic aftermarket unit.
good thing this isn't my daily driver......

The thing with the "after market" upper intake I had noticed is that many did not have the brass threaded inserts for all of the bolts that attach to the manifold.
Dorman seemed to have the fewest brass threaded inserts , & OEM had the most, as well as, a better PCV port on the rear......so look closely at what your are getting. I got a aftermarket one and it wasn't a Dorman, ( sorry I can't remember what it was) it had the brass inserts for most of the more critical attaching points but not all. So far the one I got is working well.....but If I had to do it again I'd probably spring for the OEM, or maybe try to find the all aluminum stuff.
Without the brass threaded inserts they most likely include self threading screws and these are way easy to over torque and strip as you go into the plastic. With brass threaded inserts your readily able to remove and retighten bolts without so much concern of stripping it out. Not that you can't strip this brass threaded inserts out but it is harder.
Also note the rear PCV port on the rear....This where the one I got seemed to fall short. The fitment was a bit sloppy in a area that is prone to vacuum leaks ( the infamous "elbow") & it came with a couple of different options to put in (depending on your application), so, you and to pick the one that works for yours. Now to my knowledge it hasn't been leaking, but why add to already suspect area.

so has no one here actually put an aluminum upper and lower on a non-1999 model?
seems like everyone here recommended this, but now that I got it, there is 0 support of these components
that hole should have a block off plate or a tuning valve, but if I just through a tuning valve in there to cover the hole, I will probably fail smog because the techs will think I have something that is not hooked up
