JWT are not regrinds, they start with a new billet cam, and grind it to there spec. They will just drop into the head with out any modifications.
PDMs SOHC cams are all regrinds requiring the towers to be milled.
PDMs new DOHC cams are new billet cams, then ground down to the specs they want. The will just drop into the head with out any further modification.There old DOHC regrinds needed to have new shims installed to take up the changes in the cam profile.
