hello

I can have a set of brand new coils out of GM GEN V engines, at my choice the
ACDELCO 12619161 GM Original Equipment
W/SQUARE SHAPED COILS; SERVICE COILS MARKED MELCO
OR I can have also
ACDELCO 12674754 {#12658183} GM Original Equipment
SERVICE COILS MARKED DELPHI

since those are absolutely for free, they should be a good improvement over the LS2 round coils I currently have on my 383 LT1 with EFI 24x setup (BTW they're not original ACD)?
ACDELCO D514A {#12573190} GM Original Equipment
DELPHI; 2nd Design; W/ROUND-SHAPED COILS AND MARKED 12573190
just to talk a bit, LOL, maybe they're not compatible ...
bye
