Re: DOHC Front adapter plates

For the ZL-VE head...yes correct yet even the last b6 RS had
raised ports and S-VT as well but had Z had the more efficient
shallow style efficient combustion shape found on motorbikes.

There is even more potential with slightly worked ZL-VE cams,
40mm bike carbs, headers and valve springs for 8000rpm.
An A15 bottom end with 78mm ZL-VE pistons and H beam rods
will have extra A15 stroke, CCs & higher possible redline
to achieve that power with reprofiled cams.

Funnily the 1.5L has 78.4mm stroke the 1.6L 83.4mm which
are very close to the A14 and A15 etc.

The weight difference of the Z head is also amazing due to
its narrower valve angles, quoted 15% lighter by the same
guy that was doing the B6 and ZM hybrid below.

The good news is, both heads will work with same plate
so more option for heads at least for all interested.
