Sealing 3.2L Cylinders with 3.0 Heads

Hi Folks,

In one of Wayne's tech articles - he mentions the 3.2 cylinder is interchangeable with 3.0L cylinders, but offers the caviate that the 3.0 requires a gasket between cylinder and head and the 3.2 doesn't. The 3.2 cylinder has a slight slope, the 3.0 flat with a groove for gasket. Then suggests this difference is over-comable but goes no further.
In addition, I'm struggling to find the differences in the mating surface of the heads also - are both flat neutral, or does the 3.2 head have an inverse slope?

I've done a lot of digging here, maybe my search terms are wrong, But I would be hugely appreciative if folks could direct me on best practice to mate these parts with proper seal.

Warm Regards
Tom.
