Just a note on the OEM aluminum head compared to the new production Aluminum heads. From talking to some of the reprodution places, the Aluminum heads they make today do not exibit as much head related expansion and are far stronger that the OEM aluminum heads. I guess it a difference in the alloys and heat treatment that is done with the newer heads.
