Bug engine

[Doeboy]

I've been rebuilding (tidy up) an AS engine that came from a bug. Now I know its a straight swap engine wise and I have the Cobra adaptor to sort out the case difference.
But my main question is what tinware will I need to swap over as assuming there is a few differences.

Thanks in advance for any help given
