I just recently added my 1st bolt ons to my car and part of my list was getting spark plugs because i was doing Headers aswell, i did a search on here and i found that NGK TR55's were great for bolt on fbodys, even on unmodified fbodys.. so i installed them (gapped at .060) and have no problems, Runs like a champ..

NGK TR55's are the defacto plug to run from what I've seen around here if you're putting plugs on a stock-internals, no-nitrous LS1.

No, By all means do them if you have too right now.. BUT when you do LT's i would go ahead and switch them since its alot "easier".. its really not that hard to switch plugs IMO but thats my 2cents on that
