Dual Port Cylinder Tin for Buggy Style/Exposed Engine
This isn't as good as original tin. This is what's available, and it requires some effort to fit. We use this tin every single day on our engine builds, and it requires the following modification to fit correctly:
The #4 exhaust port area needs to be trimmed back. if you place the tin on your engine you will see where the tin is angled and goes over where the exhaust mounts.
This is what's available aftermarket and it is THE SAME from all manufacturers.
You are buying a PAIR of L/R cylinder tin for dual port heads.
