The Pro MAXX MAXX Series is taking affordable performance cylinder heads to the next level, since there are no comparable cylinder heads available. The all new ProMAXX ultra smooth, Grade A 356-T6 aluminum casting, is CNC machined to create the perfect platform for newly developed runner and chamber designs. This is combined with a 5 angle competition valve job, diamond honed bronze guides, hand bowl blending and professional assembly all performed right here in the United States. ProMAXX MAXX Series cylinder heads produce out of box performance that outperforms anything in it's class.
