I wanted to know if the older Mugen Valve cover from a few years back had the different center like the new ones do. I want to buy a mugen valve cover but I do not want the spark plug cut to be different than stock. Thanks for the help

 

There is only one Mugen Valve cover for B-Series, unless they just released a new one, and that one has been disco'ed a little while back.

your engine bay is going to be like the briefcase in Pulp Fiction.
