Maple Ridge, those 346 heads ( last three numbers ) are IMHO the best factroy iron heads out there to work with. They will flow around 308cfm with a 2.08 valve with the right work. ( out side of Max wedge stuff which is expiencive) They also respond real good to mid level head porting. Its hard to put money into factory iron anymore but these heads are worth it.
