Superformance makes a very nice gasket for the W2
Though it does not answer your question, X2 with the above.
Superformance W2 gaskets Maybe mock up with what you have and see which ones line up the best.
Thank You Bad340fish and RMCHRGR
I have recently upgraded the material selection and thicknesses available for both the LA 4-bbl rectangular and the W-2 Oval port applications.
You can now get them in our Premium MicroPore-15 material in .031", .047" and .062" thicknesses.
W-2 port 2.100" tall x 1.415" wide
These are in fact so new all I have is a spy photo of them on our warehouse shelf
EDIT:
P.S. Gasket thickness is used like a shim. If the ports on your intake sit low compared to the head you need to add gasket thickness. If they are sitting above with the gasket you have a thinner gasket will lower it for better alignment. One does not necessarily seal better than the other
