You can put the heads on. You'll need to block a small coolant hole at the front of each head. I would not consider this as a good change. 8CM heads have pretty large combustion chambers and will lower your compression ratio. Hence power.

The compression was lowered on the 255 to compare closely with the ratio on the 239. I guess they were worried about detonation under extreme load. EAB heads would be better and 8BA are next in line.

The universal ribbed radiator hoses may work if they are still available. It depends on what radiator it's connecting up to.

kurt: Installing 8CM heads on a 59AB is a bad idea. You gain nothing. Don't do it.

Besides, the early heads looks so much better!
