Before I start removing plugs/wires from my '92, does anyone know the recommended plug and gap for the 383 engines? Anyone have good personal experiences with a particular plug?

90 ZR-1 #2547 (Turquoise Metallic/Black)
92 SNAT 400 (Polo Green/Beige Convertible)
95 SNAT 450 (Black/Black Aerobody Coupe)

I had AC plugs, but had given strong thought for NGK's TR55 pugs

G ap is suggested at .050. but I might argue .045.

Perhaps others have insight. And tips on #8 r&r
