I have 180 headers and "high-port" heads.I changed valve springs this week and since I had the plugs out ,and it is a nightmare to change them,I put in a new set.I had no problems with the Autolites.I used to race a Mustang with NOS and NGK was the best plug that I ever used.I also run them in my '01 Lightning
with great results.I took it for a drive today and it runs better than ever(except for a oil leak)
