Slant 6 Aluminum Performance Head

I see little point in a aluminum head other then it's kewl.

A ported out factory head takes a /6 out to fairly radical level not much more room for NA power.

/6 is fairly light anyways lighter is always better though.

Basically if some offered a cnc ported reworked factory head that peeps could just bolt on it would 90% of what a aluminum head could offer most anyways.
And if they sold like hotcakes then some company might do aluminum if they seen a market.
