my brother is very good at porting. he had the best percentage of flow in his class at NADC and he has done some major porting on his cars.hes out of state now but if your interested, he would probably port a head for you when he comes back from this job.im not sure what he would charge but it would be a professional job im sure...assuming he'll even do it( hes a volkswagen guy and doesnt like to work on my nissan...)
