Hrmm defiantly can be helpful i am always looking around at different things.

I do know that the mz's benefit flow wise by the valve stem size reduction from 6mm in the vz's to 5.5mm in the mzs. The guide is also almost 1/2 the size as the vz's guides which can see helping keep the flow less turbulent.

On this V6 build here i am actually converting to a 5.5mm guide (for other reasons) and stem valve (high flow design that i have) i wish i had the flow bench now so i can really see if there is a difference
