Spark plugs advise

[Creep]

Hello Guys
I am running a 1994 LT1 that I have converted over to LS electronics. I am running block hugger headers. So I need the shorter spark plugs. I am having a 2 cylinder miss at about 4500 to 5000 RPM. And I got to thinking if this has been changed to the 96-02 coils. Should I be running the spark plugs for that coil and electrical set-up. And if any of you have done this. Tell me what plugs you are running. Thanks for the help.

block hugger headers don't have enough clearance on all the ANGLED plugs in the LT engines-Accell has some shorties plugs
