They should bolt right up. I can't remember the hood on the 54. That could make a difference on how the rubber mount's line up.

If you have both engine's, just compare the power head's, and how everything is attached.

Yes, the powerhead will work. Only changes will be the intake manifold, as I believe the '55 did away with the thumscrews on the cowling. The thread into tabs on the intake manifold, so you'd have to swap your '55 onto the '54 powerhead. Other than that, all else is the same.
