W5 vs W2 inlet manifolds

They will bolt up with no mods
I had a pair of w2 heads that were ported to rectangular shape to match w5 intakes.

How do you account for port height difference?

I had both W2 and W5 heads and still have W2's. When I had them both the thought never occurred to me to try and swap intakes.

If you have one set of heads and the other intake, seems to me either find the other heads or the other intake.
