Twisted6, It's the latest issue of 12 Port, I got it yesterday.
Your right the valves are staggered. It's not a cross flow head. The top end sounds bullet proof, shafts and rockers. Comes with special hardened pushrod ends, rocker cover, exhaust plate & gaskets,and the intake manifold as mentioned previously. It also includes the head bolts, the 351 Ford bolts.
There will be some configuration problems to work with. For best combustion you need to run flat top pistons. The intake and exhaust ports are on the opposite side of the head, the sparkplugs are on the drivers side. Since the intake ports are canted (looks to be 45%) you will have to watch your overhead clearance. The header will have to clear the distributor, oil dip stick, and starter. If your running a coil in cap HEI might want to go external coil for additional room. Even still considering the potential of this head well worth the effort. I can see myself introducing bent things to the wonders of an old straight six.
