I was just about to order my hooker 2055 headers for ACS when I ran into a snag. This will sound dumb but how many O2 sensors came on our car from the factory? I have a stock 87 IROC 350 L98. I though there were 2 O2 sensors. I guess I just assumed because my buddies LT1 has two sensors. I looked under the car and could on find one sensor.

How many O2 bungs do the hooker super comp 2055 headers come with and how many O2 sensors does my car have stock?

 

Your car has one 02. The Hooker 2055's have 1 02 bung accordingly. OBD1 LT1's had 2 02's and OBD11 cars (LT1 and LS1) had 4.

 

Alright thanks. Just supprised me that it only had one O2.

Just placed the order though ACS. Getting the headers and y pipe ceramic coated. Should be nice.

Do you guys have any other sudjestions for things to replace while I'm doing the headder swap?
I plan on getting AC Delco plugs. Wires, not sure what kind to get. Who makes a replacement wireset. I don't want to have to crimp my own ends. I think I'll need 90º boots on both ends. Looking for 8 or 8.5 mm. Does anyone know of a good premade set?
Also planning on getting a set of wirelooms from madeForYou for the center bolt valve covers.

What about a heat shield for the starter? Is one really needed?
What do you think? Is there anything else that I'll need?
