"Ported heads" may sound simple but really they are not part of a tight budget. ANYTIME a professional goes into a set of heads to increase flow/velocity it is $$$$$. In fact it is so expensive that it very quickly approaches and matches the price of a set of Eddies. If the price of a set of Eddies is not in the budget than I doubt any type of porting is. That said the goal must be realistic for the budget.
