i see a note in there that says use only with edelbrock heads, very interesting, i would love to hear the idle and see some dyno specs torque curve numbers

[pyagid]

also says use a specific crane valve spring with stock heads

They probly get their springs from Crane...I think Comp cams are made by Crane as well.. I know Edelbrock cams are.
