bob: that's what i got for my hemi dart clone(dvorak ones). i haven't run them on the motor yet but they look of really nice quality and the only change i had to make was some clearencing for my valve covers on 1 end. i got them mainly because of the ablity to remove the rockers if needed with out removing the center head bolts. dans reputation is pretty good and the couple of times i talked to him he was helpful and didn't seem to be in a hurry to get off the phone even though he had already made the sale. they do change the geometry some (for the better) so keep that in mind. dave
