If you take the sanding method, remember to spray primer or something similar to show the uneven spots. I did this for my T2 flange on a home go-kart project.

+1 Belt/disc sanders are NOT the tool to true a flat surface. Might as well use a sandblaster to do it.

Most engine machine shops have a really nifty horizontal grinder that can flatten an eight inch warp in a millisec. AND, it is flat. Of course, you'll get charged an hour's labor, but ........

OMG, thank you so much. Our forum was about to be shut down permanently for a 10 day old, one letter spelling mistake. Again, thank you.
