plenum help please?

Hi, I just changed the plenum gaskets on my 92 cavalier, 3.1 MPFI. Problem is the plenum doesn't seem to be sitting correctly on the intake. Looks like there is 1/8" gap between the two, and the gaskets seem loose. The bolts have a metal sleeve over them that appear to act as a spacer and the bolt and sleeve sit inside another rubber sleeve. I torqued them down to 88 in lbs. What's going on? Am I doing something wrong? Thanks!

Sounds like you didn't get the right gasket. Probably wrong year.
