I will be getting a set of these heads w/L76 intake. I'm looking for recommendations for a shop to port/polish, add new springs and valves. I am in the S. FL area and would consider up to mid FL. Any experiences?
click on Norris Motorsports under Tuners section, they have shop in Almonte Spring and Pompano, contact Mike Norris. Or Revxtreme in Tampa and Fort Myers. They did my headers and tune and I' plan to do head and cam with them also. I wouldn't go Breathless Performance, I heard not so good things about them.
Reading articles in GMPP mag, LS1 Forum threads say that these heads have a great capacity for horsepower gains. Also they look stock for warranty purposes.
You can give Next Level Performance here in Orlando a call and talk to Jeff @ 407-682-7223. I have talked to him about this same setup for my vette and he will be able to help you out with it.
