Which one? MSD AL6 or MSD AL6-2 for my stroker 418 (340)

So to update.. I got such a good deal on a lightly used MSD 6T 6400 I've gone with that, seems a good unit.. But then anything is better than the factory ECU and ballast I guess.... just been looking for a "How to" guide on totally removing the double (4 pin) ballast resistor but they all get confusing with people saying different things and either agreeing or disagreeing with previous posts.. so none the wiser to the correct way to do things, I could possibly figure it out but would rather get it right first time.

I've looked previous but had same issues as I've got a GM HEI module sat here too with the plan of removing the ballast.

So if anybody can reply that is running a HEI 4 PIN GM conversion it will stop ANOTHER HEI thread lol!! I figure I need to do this either way be it it MSD 6T or just the HEI
