Here is the website with a wonderful how-to for removing the plenum, coil packs, and starter. Bookmark it now!!

http://www.bcvettes.org/

Click on "How To" on the left and away you go.

When you are putting everything back together, make sure you get the 12 plenum bolts tightened to 19 or 20 ft/lbs! Just using the hatch removal tool, we had white smoke coming out of the tailpipes because coolant was seeping into the cylinders. A torque wrench is a very useful thing to have around, get one! You can use it to tighten all of the bolts with the exception of #4 and #6 unless you can fab something together, it is a tight fit.

We were able to re-use our plenum gaskets. When you are ready to lift the plenum off, use a utility knife and a flat-head to lift up on the gaskets, if you are patient they will come out A-OK. Get a set of replacements, no telling if you need them until you do.

Thanks Much Chedberg,
Good advice about the torque wrench, I found a write up on taking the plenum off in the Chilton manual... They have all the ftlb requirments for every bolt and I purchased two torque wrenches, one from 0-80 pounds and the other from 20-200. Only 40$ for both, couldnt pass it up!
I also found extenders and narrow sockets at a locla hardware store that enable access to 4 and 6. Thanks again!

Remember to up the torque a little bit when you use the extenders, as the shaft actually flexes under torque.
