Sorry to dissapoint you bigbroncomike, but the 600 head definitely wont fit on any other model, let alone a 250. The combustion chamber surface is much larger (obviously being a 600) and it has 6 bolt-holes in different places to the 250's 4 bolt holes.

No worries, the 85 head will be the twin carb head so it wont fit on the single carb 87 model. you may just have to source one from the wreckers or something
