no, all i ever asked to see was ur numbers from ur head porting job, thats all, then u get all worked up. u said porting a small block chevy head is the same as porting a LSX head. DEAD WRONG. u can take i belive up to 6mm out of a sbc head to make it flow great, wiht a lsx, its only takin up to 2mm out. then u said porting ur set of lsx heads, that u dont even need a flow bench to check ur numbers at all. when hand portin u should, and i would have a flow bench to check numbers. then i said that Dart CNC’s there heads and then smoth out by hand.
