For any of the guys who've upgraded to an after market header, could someone do some thorough measurements for us?
The gaskets are no avalible out side the dealer at the moment so it's a little tough for me to get at the moment. I'm looking for the port diameter, spacing between the ports, over all length from far end of port to the other far end, and bolt pattern measurements would be nice but also tricky.
Would really be a life saver if someone could help a guy out.
