I don’t think Engine Pro manufacturers their own parts. I thought I understood they license or wholesale other manufacturers under their name. They do offer tons of good stuff, so their name does not worry me at all.
Here is a link to the Expo where they discussed the Chevy version Mayhem heads. Makes me wonder if the Mopar versions will be just as good. Hope so.
