The old style airbox, filter and starter cover (must use old style for all three) doesn't breath as well as the new style. So this will leave you running a bit rich. i wouldn't worry about it. Build it, run it and then adjust jetting if needed. Jets are cheap.

if you look at the diagram here you see the windage setup on top of the block. Seems to me part #2 is for the old style with a hose to the Right intake and Part #3 is for the new style.

This shows an old style starter cover and windage assembly. You need it all.

This shows old and new style starter covers. The one with the slots (rather than the scoops) is for the flat airbox)

The new style windage feeds both sides.
