Alex,

If you don't have the foam-like gasket for the air metering unit, you could improvise by using a thin foam material commonly used as packaging wrapper for breakable items like dinner plates or wine glasses. All you need is to seal it to keep dirt from getting inside the air box. It does not need to be sealed air-tight!!!! I hand tightened the bolts firm and snug.

For the throttle body, the o-ring seal is all you need. Unless the o-ring is old and not sealing well. The butterfly valve in your throttle body should sit and close with minimal gap. Yours seemed to have quite a clearance (?).

Continue your good work and get the engine running before the cold weather arrives!!!! You need a fuel gauge kit to make your start-up a breeze and pressure test the engine before you install it back in the car. Vacuum/air leaks is the Achilles Heel of CIS. I like to test run and tune an engine before putting back in the car but this is not for everyone because you need to have an engine test stand to do it and makes life simplier. Keep us posted.
