My dad sent me some heads he ported several years ago. They're 6293 heads he ported using the Buick Performance book as a guide. He's a master machinist (actually a tool and die man). I want to use these, but I'm not sure if the porting job would be good for a street driven, stock turbo car. He built these to go on a pretty radical N/A 3.8 he was building for an AC Cobra kit. . . What do ya think?![Confused :confused: :confused:](https://cdn.jsdelivr.net/joypixels/assets/8.0/png/unicode/64/1f615.png)
