Spark plugs for a carbed S5?
 

I have a 89 GXL with a dellorto carburetor that I just bought and I am wondering which plugs I should use the older BR9EQ-14's or the newer BUR9EQ's since it looks like its running a distributor and the stock coil/ignitor? I read that their is a diference with capacitive discharge ignitions. Also what heat range plugs would you recommend since it has a carburetor? Thanks

Well, I read up some more on 2GCDFIS and all the other ignition conversions, and im still not quite sure what my setup is called, so I can read up on what spark plugs would be the best to use. So I will try to describe what my setup looks like it just has the 2nd gen coils going to the distributor and then from distributor to the plugs. So does anyone know what spark plugs would be best for this setup or does it even really matter?
