Hey Steve,
It's a tunnel port intake and heads, the synopsis sheet is the only place a wedge intake is referenced. An error on their part.
Aside from the shape of the intake runners, the easiest visual clue on the tunnelport is the 6 intake bolts per side.
Jerry is right, no need for low compression with N2°.
I'm not a fan of nitrous even on a cheap motor, I'd never consider it for a side oiler if I was building one. Just my opinion.
