Re: Vortech Heads
Obviously not taking in what you are reading.
Some of the best performing heads ever to come out from GM on a stock engine , they outflow every cast iron SBC head ever made including the Bow Tie race heads.
Stock they have valve lift limits but that is easily overcome and heads require a Vortec only intake
