You can not make an intelligent cam selection without knowing a lot about
the cylinder heads.. so having identical ones is interesting but not
quantitative.. There is a big difference between an old set of rectangular
port heads and a new set of dart cnc'd heads flow wise. and the cams for
each are quite different even if the goals are the same.
