Lets discuss this before you do it. The biggest question is why? I run the IDA's and I had a friend with the IDF's...the IDF's are much easier to tune since you can do each barrell individually you get a much better street car. If you have any cam in that motor forget them...short runners mean you can have no exhaust leaks at all.

Pros: They respond like a scaulded ape..and run through the RPM like crazy. I love the look and once you get them set you are golden.

Cons: Less cam (takes out the lumpdy lumpdy lumpdy sound). Can't have any exhaust leaks. Get really really ****ty gas milage...If you don't run screens then you can get dirt or water in them and thats bad!!!
Expensive!!!
