will J heads work on a 318? And many many more questions.

Thanks Rumblefish.

I have no real idea how to port the heads. Are you talking about the ports where the intake matches up as well as the exhaust? Also, what do I have to do to get the 1:88's to fit. Are the direct replacement? The engine is a direct take out that only has 70K orig miles on it. It is a 69 though. I wish I had the money to put different pistons in, but at this time, I don't. About how much does it cost to shave the head a little?

As for gears, I am going to be running 3:23's. I had 3:91's, but they are not highway gears. I plan to drive the car and drive it allot. I will build another car as a race car, this one is for the street. If I get the Demon I am trying to work a trade on, that one can be a street/race car. That being said, I still want the Duster to perform and I want it to sound good. I am assuming that with the crower cam and how everyone is saying that it's big, it will have a loap? Also, I am running 340 exhaust manifolds, not headers. The manifolds have been ported out a little by the guy I got them from. One other thing I noticed about my intake is that one of the ports is allot smaller than the others, I will post a pic to show in a minute. Is there a reason for that?
