What is the difference bewtween dohc vtec intake manifolds and dohc non-vtec intake manifolds?

depends on which motors specifically. For instance, a GSR manifold will not bolt onto an LS. It has a water passage that I believe the LS does not and the intake ports are different shapes/sizes.

bolt pattern for one im not sure of other differences like port sizes though if that's what you're asking

I have a b16a head, will a b18a intake manifold fit on the b16a head? Tried the search, all it comes up with is the difference between gsr and b16/itr heads.

What motors are you specifically curious about? I.e. B16a, B16b, B18C1, B18C5, etc. An H22 intake manifold wont fit on a K20 either.

The only similarities that I am aware of are B16a and B18C5 (anyone know if B16b is?) IM are interchangeable. B18b and B20 IM are interchangeable (anyone know if B18a is?).

Looking online at aftermarket intake manifolds, there are different part numbers for B18a/B18b and the B16a motors. I would tend to say no, a B18a manifold will not work on a B16a.
