NGK TR-55 plugs gapped at .052-.057 or Autolite 764s.
Both copper and will give the best performance. They do not last as long as platinum but who cares?
i agree, I use TR-55's and swap them out every spring even though the strap has semi sharp edges. less than 10 bucks for a easy swap is not bad at all.
for the original poster, don't over tighen plugs, use anti-sieze and once you get the hang of the last 2 passenger side plugs you can swap them in 20 min.
