Can anyone give me a step by step guide or something?

Maybe a couple of tricks to help things along the way?

Thanks.

 

Depends on the specific headers you are trying to install. Procedure will vary. Here's a writeup I did for putting a set of JBA's on my Formula many years ago. Only difference with 93 will be there is only on connection on the passenger side #8 primary for the combined EGR/AIR. All other years have a separate connection for EGR and another for AIR on the passenger side. O2 sensor part # will not be the same. 93 uses single wire, unheated sensors, all other years use 4-wire heated sensors. Watch out for the oil pressure sending unit on the 93.... its right above the oil filter. Other years have it on top of the block, at the back of the intake manifold.
