Fix for leaking chrome T-stat and valve covers.

I put one of those chrome MP housings on my 440 only a couple of days prior to reading abt the warpage problems on here or Moparts.Can't remember which.
Yes,it's leaked from day one.
Today I removed it and machined the face flat in the lathe (because I've got one)
It took 25 thou to bring it to flat!!!
I'll post again after a while to let you people know if it warps or if it's successful.
