The shims should have came with the double roller set. I believe they are roughly 3mm.

and you need to have the pulley cut or else it'll lock up

Well I was under the impression no matter what pully it was it need to be machined cause the oil pump is shimmed outward to accomidate(sp) the double chain. I'm not sure bout the new sfi pulley. Someone know?

felton is correct, the newer SFI ASP pullies are machined for clearance, the older ones, the snout needs to be machined for the roller. The shims AND longer bolts should have came with the double roller.....
