01 manifold question....

[GoatSlayer]

Will 01 cobra exhaust manifold fit onto an 03 cobra longblock?
Will an 01 down pipe fit onto 03 cobra exhaust manifolds?

1. Yes. Turbo guys use them all the time
2. Yes again.

1. Yes. Turbo guys use them all the time

But doesn't the exhaust ports on an '03 head have a more squared-off shape instead of the oval shape of a '99/'01 head? I thought the exhaust manifold would match the ports for their respective year, but maybe not.

An easy solution is if using 03-04 heads and have 01 manifolds,
port the 01 manifolds to the 03-04 size.
