Tomorrow morning I'm going to replace my header gaskets with the right ones (FEL-1415)...and I figure the port holes won't match to the AFR 165's perfectly...what do ya'll think I could do to trim them...just go at them with some scissors???? I messed up my last header gasket set (different cheap ones made of a metal substance)...by using scissors...
