So, what I am trying to do is adapt a b18 bmc race manifold to an A20 sohc. Normally it's not a big deal to just re-drill the top holes and bolt it on.
From what i can tell,The bmc race manifold fuel rail mounts will not allow me to do this. What I need is a simple flat flange 1/2" to 3/4" in thickness with stock b18 ports. I would also like all the mounting points drilled with 1/8" holes so I could add studs to certain ones. Here's a pick of a s2 intake that I modified and ran for the last few years.


Any help would be appreciated.

 

There's a good chance someone here already has the dimensions but if you are still looking and it's been awhile, we can CNC machine whatever you want.

Haven't done any b-series intakes so I'd have to head over to the junkyard and pick up a cheap intake.

 

I don't know how all that stuff works. What about a gasket? PM me a price.
