  Hi Paul,
Well I have cut the standard manifold down by 1" and the pipes are 9"
above the shaft center line and there is still room for improvement.
Tomorrow I will cut another 1/2 " of the cast original manifold and that
is as much as it should be cut.
This will give me 8.5 " above the shaft center line to the top of intake
pipes.
Attached are three photos of take two.
I would still like to get one of your cast manifolds but this one will
have to do until yours is completed
Regards Don

I would not go any further than you have to Don. The further you go the
more out of round the runners become and the worse match it makes with the
round or squished oval pipes.

Here is a picture of the one I cut down too far.
