I'm really looking forward to seeing that episode of Horsepower. As others have pointed out I'll be surprised if see a direct comparison of stock heads vs Edelbrock's heads vs Rich's heads. I'm guessing that they will also change the cam and manifold and use Rich's heads on a more performance oriented engine to avoid a direct comparison. If they did do a direct comparison we know how it would come out...
Stock heads,,,, good
Edelbrock heads,,, better
Rich's heads,,, best
I'm hoping that Lamar puts together a great engine combo with a fully ported set of heads. I'll bet he'll make a lot of viewers think twice about the old "truck motor"
