We dont have any alloy heads made here in Australia except for a Cleveland head.

As far as SB Chev heads we have the new EQ cylinder heads being made here that get shipped to the states and they do a brand new 906/062 casting vortec that blows the oem out of the water like they used in the latest issue of PHR and called it a sledgehammer.

The alloy heads however you think come from OZ are made in China All Pro Comp stuff is.
