Honestly, I too feel that changing your spark plug wires is the best Place to start. When your changing them out for your MSD wires check to see if there are any vacuum leaks, and definitely change out your fuel filter. If none of that makes any difference, check your fuel pressure, see if you have enough pressure. Don’t be afraid to back track ether, have you changed any sensors before you had the headers installed. And, another thing have you tried to disconnect the battery over night and reset the computer. Just for the hell of it, look at your Throttle position sensor, dont take it off just check to see if its been moved from its original position or if its loose.

That’s good to hear, honestly I feel some of your pain, 5 years back I built an L98 Lingenfelter engine for my 89 GTA, I had a lot of problems with the OBD I computer that was in the car and trying to convince it to run right. But, like anything you try things some work some don’t and you learn. I like these LS1 engines, I’ve been learning different things about them every day.

Hello just joined.Not sure where to post this but I have a L98 C 4 Corvette.I found the compression has decreased by 50% in most cylinders.I have a chance to get a Lt1. Will the LT1 fit in it's place?

My car was doing this as well. Did you remove the AIR and EGR? I got rid of those (no egr 4 me) and that vaccume manifold under the cowl and that did it. Could not give you one reason why it did it or what the problem actually was.
