John,

The work that I have been involved with has been on the Dan Price 4 port Cragar head.

Basically, the horizontal flange is removed and replaced with a flange on approx 45 degrees. This takes some welding, have not had any problems, it is a really good casting.
Results, pretty good improvement since it allowed for larger throttle bodies and injection stacks. It did quickly start to show up the other limitations in the head with valve placement and CC shape.
IMHO, the gains are not worth the investment if the vehicle is street driven. The supplied manifold attachment is difficult but workable. If this is done to make a hill climb motor, you had better make the investment in the bottom of the motor.

Stay safe, John
