Odessa heads - take a look.. Looking for input *solved

Also, what quality of valves to they use. I plan on calling them tomorrow.

Copied from their advertisment
ODESSA*CYLINDERHEAD thoroughly cleans, inspects, and pressure tests all our cylinder heads. All seat and guide work is performed as needed on the lastest state of the art Serdi or Sunnen seat and guide machine. The head then moves on to a Rottlier CBN resurfacing machine where it is cut to the required RMA finish. We then install a quality valve seal and pull a vacuum on each valve to insure their is a perfect seal between the valve and the seat. All machine is work performed on the latest state of the art equipment. The head is complete and ready for installation.
