while I was doing some porting on my head I found the ports to be very straight untill they reach the manifold where they have a decent angled change, from here they are dead straight to the throttle face. Now I have a friend who was give the offer of a custom angled spacer plate made up by some place called HSD that will correct the angle and has apparently been proven to flow +10%.

- Do you guys think that such a manifold would show any real world gains?

- what about the fuel flow? right now it aims right at the middle intake valve, if i change it it might hit the floor.

- I would still run curved trumpets but mandrel bends, would that negate any gains?
