Talked to Jason at AFR again today my heads are in the mail and should be here by Friday. They are including a set of 1011-1's. He told me the fire ring is not hanging over into the combustion chamber anymore than they do on his personnal car. When they get here if they don't look right, I am going to do some seious measureing and see if I can figure out the problem. One of my heads sealed, so their should be a difference between them.
