Nice! At the risk of going a little too off-topic..
What's the angle of the intake ports/runners in the head and does it match the angle that the manifold runners end up? Don't want to assume anything from the casting or flange position as the inside can be different...
Reason I ask is because at high rpm's if there's a mis-match in the angle(s) of the manifold and the port runner where they meet up then there's a good chance that the air flow will detach from the wall and start producing a lot of turbulence and as a result a reduced cylinder fill. This can make the torque drop off (much) too soon.
BTW... As you are building a high-revving N/A there's only 3 letters I want to give you: I T B
Hmmmmmmmmm... Yummy!!
Will allow you to run much wilder camshafts and still have it idle decently compared to a plenum...
Bye, Arno.
