I'm going to have to order the comp cams break in add, it didn't come with this cam for some reason. I've ordered several cams and all of them came with add except lunati I had to pay extra for the add oil. I don't know maybe I paid for it and didn't know it on the other cams I just thought when you purchased a cam the add oil cam with it. I did realize I would have to use a additive with the cam break in but I was really looking for a good oil brand to use with the break in and after to keep it alive. I don't have dual springs I have the 1110 springs that come with the rhs heads, 120# seat and something like 310# open. I did talk to comp cams when I bought this cam actually they suggested it and said these springs would work with this cam. Any thoughts on the oil pump question?
