[urq] WX head build recommendations

[Andrew B]

So wait, can an MC head be used on a WX engine or does it require
modification?  I apologize in advance that I didn't get it the first
time, but it sounded like you might need to close a passage?

I'm about to perform a head swap myself, and I'd like to do it right.
