That pic I put up was an entrant to the Engine Masters competition some years back.
Most, if not all, aftermarket blocks have the provision for that extra head stud...many aftermarket cylinder heads do also.

Just up your alley. Typically a rectangular port intake will be used and the floor of it's runners epoxied up, and then matched to the heads.
There are only a few companies that get/use that cylinder head....you won't see it in the Brodix catalog but it is available.
I have the flow #'s here at work some where. If I find them, I'll put them up.
Edit in, found them:
Runners average 301cc
Lift / Intake / Exhaust CFM at 28"H20
.200" 170 126
.300" 250 177
.400" 307 212
.500 347 246
.600" 373 267
.700 384 279
.800 388 288
