I love the AR series plugs from AutoLite. You cant foul them... I run them om alky for two seasons, change them, cause I think they need changed. I know guys changing plugs like I do under wear. I dont know why.. Anyways... My MP Aluminum Hemi heads (edelbrock castings) I use the AR 3933 which is a bit cold for that mild of compression, but I was running 14:1 so... AR 3934 I run with a large wedge with Moderate 12:1 compression... These plugs are cheap, and I can get them at the local Advance Auto in town, for about $25 a set of 8...
