A little off topic, but I just noticed those valve covers you got there. Any info you can provide on those?

Yea, only you will start running into a problem with them clearing the back of the alternator and the AC bracket.

are you talking about the chrome valve covers not clearing? How do you get around this?

Originally I wanted to keep my motor looking stock so I shelled out for the LT4 valve covers but now that I've got them on the car I wish I had gone with something like this.

Yes, the front of the drivers side cover is very close to the back of the alternator and AC bracket. I rebuilt my alternator and ground some off the back to clear the covers. I also used a washer under the AC bracket to left it up just enough. Her's an idea for you, pick up a set of these covers off of Ebay for $80 and have them engraved with something interesting. This pic shows the drivers side cover with a notch to clear the bracket. You could also paint your LT4 covers to match or contrast the color of your car. Since you have a 92 and have already gone with the composite covers, you know about the hose from the TB being different.
