Heads have about 5000 miles on them with a completely new valve train. this includes seals, retainers, springs, ect all from crane cams. they have a fresh mill and received a sportsman port and polish job by a local shop that has built numerous dragster motors for our localtrack " sunshine speedway " .
No flow #s but i would compare the power they put down to a stocker set of gt40s/gt40ps. + a killer spring kit
