I have an equal length manifold I made, but I got everything too hot and the head flange, wastegate, and turbo flanges are all warped.

How much should I expect to pay at a machine shop to have these grinded flat?
Thanks!

 

i would say about 50 bucks if they have the right equipment.

 

Thanks, I was just looking for a ball park figure.

thx

 

I just got quoted 30 at a really good shop around here. for just the head flange
