gaskets came and I went to reinstall the pipe and I wasn't able to because the header doesn't even come close to reaching the exhaust mount without touching the cylinder head fins. This was a problem when I first was trying to mount the exhaust, but I shaved a good portion of the fins off in the front in order to make the pipe fit. And it bolted up perfectly. I only messed with the pipe, so it must be where the problem lies. I'm super confused on wat the problem would be because the exhaust tube header looks identical to when I removed it. I guess it is possible I knocked it back when try to flatten out the flange but I am not really sure... Any guess as to what is wrong??
