Not sure if you got this taken care of but I asked Aaron at vast and this was His response:
As compared to turbo cams the NA intake cam has 7º more duration and starts opening 4º sooner, the NA exhaust cam has 3º more duration and starts opening 2º later. So to replicate the base turbo cam settings on NA cams you’d retard the intake by 4º and advance the exhaust cam by 5º. I find that by reducing cam overlap you can greatly reduce the chance of knock that is prone to happen at mid-load. With turbo cams I recommend starting with 2º of retard on the intake and 2º of advance on the exhaust. To replicate this with the NA cams you’d want 6º of retard on the intake and 7º of advance on the exhaust.
