porting cost?
OK, OK Maybe I'm a bit harsh, but I get tired of people that want to beat down the price of the work when they have never done this them selves, this is part of the reason that the price is this high, and that the tooling cost is going up let alone the amount of time that it takes to do the job. IMO this is one of the best things that a engine can have done and make HP when done right.
I'm not here to slam anyone but it just jerks my chain when anybody tries to cheap'n the process that has to happen. Most people don't realize that it takes 25-40 hrs. with a flow bench to achieve a head that will perform and satisify the customer to there needs and every head is and has to be built to a specific engine to avchieve the HP.
