spark plug ?

i recently just got 601 heads to replace my 187s. im looking for a 2 step colder plug with a non projected tip but dont want a race plug. also will these plugs stick out further(closer to my headers) than on the 187s since the plug went 3/4" into the chamber and this one doesnt?

Re: spark plug ?

I thought the S refers to projected tip?
I use the R42T (for that reason)

I think I have champions in now, RVC9 or 12 IIRC. I forget now.

I prefer the champions over the delco's just because the delco's are black oxide, and therefore harder to read vs the silver champion plugs. :2cents:
