Yessir, I gave livernois my deposit for heads and cams earlier this week...They are the only ones I trust with this motor, R&D is second to none on this niche motor, I was originally worried of the costs, but on something like this it is worth the extra dough. You pay for what you get is what the old man used to tell me. I was really just looking for a better/compatable rocker (lighter,stronger) setup I could buy and send them for my package. I appreciate the input.
