What I find interesting is a simple item like even an AOS, read their description for that component and see what you think..
Its also to be noted that bigger isn't generally better, at 3.6 the 3.2 heads are on the verge of not being effective without port work and larger valves. At this point the engine gets close to the edge of inefficiency and a narrowed powerband from the smaller port.
The combustion chamber of the 3.2 head is such that it nets an 11:1 CR factory, when you go up in displacement with that same size chamber without a specially prepared piston CR can see 14:1!!
Just some things to consider, in no way meant as a slam to MM, I just wanted to stimulate thought a bit :-)

Let me be a little more forward about MM than Jake. They have long reputation in the aircooled world of producing utter crap! Dont walk but run away from this stuff.
Consider Jake the Rolex of engine builders and MM the guy on the corner selling fake Rolexs for 5 bucks.
