I think I installed the wrong cam

Are you sure about that? I thought you had to start with a roller cam? The base circle is too small on a la. I maybe wrong tho
Positive. I've talked to Ken in depth about it. I'm still on the fence about it. I may get him to grind a small solid street roller on a stock slant 6 core. I haven't made my mind up. But he can do it.
