what plugs do I need? I have a set of AFR 210 heads for my 383 lt1 build. I am currently running a stock style plug and the tuner recommended NGK TR6 plugs. I was looking on AFR's website because a friend said he thinks I needed sbc plugs with the metal gasket and they say to use plugs with a gasket. Am I using the wrong plugs? Did the tuner recommend the wrong plugs as well? I would like to change the plugs now but unless I find out more I have to wait until Monday and talk with someone at AFR.

Your heads and most aftermarket heads are mchined for a gasketed plug. So, yes you need the gasketed version of the TR6.
Look at Summit or Jegs. Aftermarket also need a longer reach plug.
Something like this might work
