I have a '90 and just bought a Procharger P600B kit. I read the thread about plugs and ignition. I was looking for the Champion 7401 plugs, but it doesn't look like they are readily available. Does anyone use the ACs 2 ranges cooler? The number I have is 61629. Also, I read that someone suggested a taped seat plug, but the stockers are flat seat. Are any of you guys switching to a tapered seat and why?

Any other tips on installing this on an L98 would be appreciated.

Thanks

 

I ran the FR3LS6 for many years with great results on both the L98 D-port heads and the AFR 190s. These plugs will work great with what you are running. I would recommend a CDI type ignition (MSD-6AL is good).
