[DeTomaso] Exhaust port tongues

[Göran Malmberg]

The 2V manifold uses the bottom part of the runner so its no
alternative. Filling the bottom of a 4V manifold with epoxie
is the trick.

How does one make the intake manifold and header match the new reduced
ports? By porting a 2V intake manifold? With an unaltered 4V intake
manifold there will be a terrible "bump" against the port plate.
