What spark plugs?

Hey Guys thanks for the responses!

yes i did have a valve cover leak! lol
as far as timing goes, right now its 16 initial, 36 total, but i want to turn up the initial and lower the total and see what happens...however for now im going to keep it this way. Tommorow i am going to the track with it to see how it runs, will be trying different launch points and bringing a jet kit with me to see what the car likes as far as jetting goes...i thougt as well that the plugs looked a tad rich, so ill try jetting down and see what happens

I dont have a spark plug reader so its a bit hard to see in where the ceramic meets the steel.

As far as heat range goes though, does this plugs heat range look okay or should i go colder? one step? two steps? id like to go buy a set of plugs tonight so i can bring em to the track and do a fresh plug reading after a pass

thanks for all the help so far guys
