I dont know if you have aluminum head are not, just passing along what I came across.
I don't have aluminum heads, but now that you brought up warpage I did have a hard time finding heads that were not warped so bad and can be used. These head are about..008 warped but the cc's were high enough I was able to cut warpage out and get to correct cc. I had a couple heads that were. 025 warped and could not use. I wonder if these have warped. This will be at bottom of last to check after I finish healing and checking the basics first
