Ls1 heads on lq4 looking for headgasket

I'm putting my afr heads off my ls1 on my lq4. Being the ls1 has the notch in the heads, what headgasket are you guys using? Thanks!

The early 832 cylinder head castings had a recess on the edge that will leak with the original MLS gasket. Info from Motortrend article

Leak what? The Compresion Ring and Water Jacket Ports are no where near that. Motortrend isn't entirely accurate, given there's not such thing as an 832 Head.

That's what I thought when I saw the picture. Maybe coolant leaks externally? I only heard about this before never seen it in practice. There are old threads about the notched heads on ls1tech ?
