I worked on a set of lowly passenger car heads off a 460,
and boy are those things nice! Big generous ports, nice size valves,
and they can easily support 500 BHP without a ton of work...
They looked every bit as nice as anything I saw from ch*vy and
much nicer than a set of pontiac castings I recently ported, and
the pontiac's were supposed to be a good version
pretty yukky IMO... but they are better NOW with the RGR touch!
