there is a pipe that feeds a hole in the back of each head that needs to be plugged when removing the air pump and its related plumbing.
You can purchase these plugs from any of the major 928 suppliers--it's the same plug that is in the top side of your camtowers (hides the tower retaining bolts inside). be sure to also get the aluminum washer that goes with it. Mark Anderson @ 928 Int'l or Mason @ 928 Worldwide wold probably give you a pair off a junk set of heads..... --Russ

Thank you very much for the information. I'm ordering a set as soon as I finish this e-mail. I can't believe what a wealth of information this site is. Someone always has an answer & no one question is too stupid or unimportant to answer. Thank you once more.

Isn't there a 1-way valve back there so pressure doesn't feed back to the Diverter Valve? Just wondering as this may be my source of air noise upon acceleration.
