Hey guys wanted to find out what plug depth measurement you guys are using for the Stealths? Also what outer housing measurement to torque them tight to the head.

Im being told that the regular plug sizes that the 906's use are not going to be optimial (to shallow) and I wanted to check in with you guys before I do some exploratory learning. Thanks.

Stealths take a long reach plug.They have the 5/8s head for the socket.I just install mine snug and use antisieze.I wouldnt torque them more than 15 ft pounds.I run NGK R5671A-8s.I was running Autolites but the NGKs run better.I do run 12.5 domes on the street.Rocky

Yes it will.I run them on my 440 with Stealths.I have the Autolite number I pulled out somewhere.They use the same plugs as Eddys.I run 12.5 domes and its street driven.The NGKs cost me like 13 bucks for 8 with my sons discount at Advanced.They are a racing plug.Rocky
