I am looking at getting my Cylinder Heads Ported and Polished next weekend along with the Intake Manifold. I am hopping for a 30+ HP gain out of it. I was just curious what you guys have heard and or seen in this modification. I am hoping it doesn't take much more then 3 days. I will have a crew of 2 other people and we will be at the shop from 6am-8pm I think thats enough time to get it done.
