Wonder from people who have these engines what kind of headers did u use and did u have trouble making the y-pipe fitting around the oil pan from the ones u ordered. Thanks.

I have the zz430 its not in my car yet because I am waiting on the headers. I am going with some headman headers that jim pace sells. They dont have any in stock right now. They are a 1 5/8 with a 3 inch collector. They are made for the D shaped exhaust port that the fastburn head has.

 

Correct me if I am wrong. But aren't the 1-3/4 headers suppose to be better for 350 engines? Just wondering. Thanks

As I un derstand it even though the 3/4's are bigger and flow more the 5/8's make a little bit more torq .
