Looking for every little thing.
Building a forged 406 Chevy with 461 heads, any recommendations on spark plugs out there?
Being a older head I know they take a special thread or something, just can't remember where I read it.

Thanks for the input, I haven't seen much on here on spark plugs.
This should give me some choices to try.

U MAY THINK THIS IS NOT TRUE BUT AUTOLITE IS A BETTER PLUG FOR RACING I HAVE RAN BOTH AND CAN ACTUALLY TELL THE DIFFERNCE AND YES THE 303 IS A GOOD CHOICE AND YES THIS IS IN A CHEVY AND ALSO MOST NASCAR TEAMS RUN AUTOLITES
