Follow-up - I do not recommend getting these headers. Apart from the holes not lining up where they bolt up to the engine, they also have many other defects.
-Nothing lines up well, you can get it to 'fit' but not in a good way
-It does not have clearance to go under the transmission, if there wasn't a flex joint right there (which needs to bend the opposite direction), this couldn't be done. As is it is solid against the bottom of the tranny, not ideal...
-The holes in the flanges are either too close to the welds or too close to the pipe. One out of three holes fits correctly, the others you can't fit a socket over, only the open end of a wrench. With the space limitation and lack of clearance it is very difficult to use wrenches in there, 1/6 turn at a time, was loads of fun
-The precat O2 sensor on the backside of the engine wouldn't reach the bung until I removed the connectors from the bracket that secures it, now it just reaches
-Small yet annoying additions to these issues, the stabilizer that wings out right before the main cat did not come with welded on nuts. The gaskets were not cut correctly, on one of them it blocked half the exhaust flow going into the header. Last the nuts and bolts provided for the flanges were different sizes, 16mm bolts with 14mm nuts. None of these were big issues, like I said they were just annoying.
Do yourselves a favor and go with a better quality set if you want to mod your car. This frustrated the hell out of me and I am just going to have to take it back off and send it back or eat the cost due to the non-clearance issue with under the tranny.
