You probably need to get Ken to move this to the Comp and Modified section.

As I understand, Glenn Knowlton in Minnesota did the cylinder heads for the SS/CS Firebird owned by Randy and Michael Mans.
I been told Glenn passed away earlier this year; however, there amy be someone still running his shop.
