The R&D work done by Pierce Manifolds for the "new" aluminum heads was
quite large, Mike Pierce told me in the region of $40,000 before they had a
production ready head. It wasn't the wrong direction, their intention was
to produce a head compatible with stock components... they produced a
siamesed intake port aluninum head that has slightly better flow than the
regular cast iron heads a result.
However, for what it is worth, you can extract just as much if not a little
more power from the cast iron heads than you can from the aluninum ones.
Pierce also produces a crossflow design which is a different matter all
