74 225 Slant 6 Spark Plugs
Hey everyone,
I am looking for recomendations for what plugs to use in my 74 slant 6. I looked at some other posts and found that there are 2 types of heads, one with plug tubes and one without and was confused as to which plugs work with what. I have included a picture of my head for reference, but I am pretty sure mine doesnt use the aluminum sealing tubes. I have ordered two sets of plugs already and they both use the 13/16 socket size which is too large to fit. Any help is appreciated.
