Brodix B1 BA MC Heads

No experience with them myself. There are/were a couple of guys that da there head but the exact version I do not remember.

There is also the Edelbrock Victor head which is an extra bolt head.
Edelbrock are not 18 bolt only 10 . They can be made into a 18 bolt head but not easily. I'm going to order a set to see how hard it would be to machine the holes.
