Welding up a M-1 W-5 for std head?

the w5 intake wont fit the standard heads with the redrilled holes due to the w5 having raised intake ports...the width of the manifolds are different....

You know we got the ports to match up when we moved the intake fore and aft. But I think we were just looking at the bottom and sided of the port through the carb hole. We couldn't see the top of the port.

Is that were all the difference is?
