I was just thinking in the back of my mind what heads could they or even what would they want to swap on there. The 243's are some of the best already. Though other heads could increase compression ratio or reduce it but that wouldnt be something worth doing when it already had good flowing heads.
Correct. We reuse 243 casting cores. Being that this was the only cylinder head available for the application, its not like I need to keep 10 different casting numbers on the shelf.

As far as cylinder heads go like you mentioned, the 243s are hands down the best performing OE cathedral ports available.
