    That's really cool. Its neat to actually see what goes on in there in a non-cross-section drawing sort of way.

    I'm pretty sure the SAP pipes are outside, connected to the exhaust manifold.... I wonder what the hell a pipe is doing inside the head's coolant passageway under the intake ports!
