Default warped header flange

How can I fix my warped header flange? Ive thought about trying to use the bolts to pull it in but with it being an aluminum head, I wasn't so sure.

thoughts?

Have it surfaced or put it on a belt sander.

My turbo flange is warped but I just use the bolts to pull it in...

I was thinking of bolting them to the old manifolds and heating the flange while tightening the bolts to see if that helps

I used a big, flat file to get the warps out, then surfaced it with a belt sander-like machine in my shop (no longer there, as it died).

I thought you had ARP exhaust studs? If so that would work a lot better than bolts.

I use a large belt sander at a local metal fabrication shop.

I do, but it warped so bad I had to hammer it off ruining the threads on a couple, so I have mostly studs and 2 bolts
