therefore the gasses flow across the head hence cross flow. You will find
that the majority of modern European cars have cross flow heads, you can
also find crossflow heads on the Dolomite 1850, Dolomite Sprint, TR7 and
Stag. >>
The advantage with a cross flow head is that the intake and exhaust ports can
be optimized rahter than being squeezed in to a small space around head bolts
and such.

The valve gear would definitely be a
mystery to me unless it proposes to convert to OHC or have one rocker across
the head for each exhaust and one sideways for each inlet (very odd).
The ports can be snaked around the push rods with minimal problems, at least
this is common with a push rod regular V8. the rockers are inline and
sometimes on a common shaft. For a really interesting push rod/rocker
arangement, look at a 70's Chrysler 426 Hemi the intake push rod is at a
severe angle.
