Trevor, the reason for the 7 degree pull on the cams has to do with how Delta Cams grinds theirs. They use profiles from camshafts they have already. In saying this, they used a nissan profile for us and did what they could to make it work with our cars. This is what I understand from what we had discussed when first looking to do these. If we use the SVX exhaust profile, I do not believe we will need to retard the profile since it is basically what we want from the get go
