I have a Powerlab plenum spacer on my Z now but I have to take it off and put the stock gasket back on before I take my Z in for a oil Consumption test. I dont want them to blame the oil Consumption on my plenum spacer so I need to take it off till after the test or new motor install. I need to find out what bolts go where when putting the stock gasket back on, also need to know the torque specs for the plenum bolts. Thanks much for the help.

Only thing I remember tricky about the upper plenum was a guide pin. You use the pin to align the plenum. Forgot what I did with the pin after installing the plenum.
