Porting the exhaust manifold

[redline24]

Do you guys think there would be any power to be gained by porting the exhaust manifold. I dont think it would be as much as a header but I think you could gain 5 maybe 10 extra horses by port matching the head and exhaust manifold. Also by opening it up a little to the exhaust side. Let me know what you guys think.

Check some stuff online first, I remember reading/hearing somewhere that the exhaust manifold is already port matched to the head. I could be wrong though. If I am, exhaust work on a supercharged car usually works well.

I am thinking about pulling it off this weekend to see how much I could work on it. I will take pictures of how bottled up it is.

I was also thinking about this, I wonder how much room there is from the port to the water jacket. Anyone want to sell me a head, real cheap so I can do some grindin??

I think ported exhaust manifolds would help, if yours are anything like a grand prix's manifolds there is alot of restriction.
