I thought you just picked up a header really cheap on ebay?
FU Tuning
I did but it was for the 2.4 head I put back on my stock bottom end thats in the Z. This is what I took off of the car and will go back on later after I put the built engine with 2.3 head in the car. Then the engine that is in the Z now along with the header I bought will go into the convertible. I know its a couple extra steps but it keeps both cars running while i get the built engine together.
