I use whatever 'premium' plugs Rockauto has listed for the 5.7 at a good price (can't remember what I ended up with exactly.), and haven't had any issues. Correct temperature (which rockauto listing seems to be pretty good with.) and gap to spec when you receive them (I don't trust pre-gapped plugs, they can be knocked out in transit, etc.) should be good enough.
