I rebuilt my head and purchased the Calmini camshaft for more power. When I recieved the camshaft I imeddiatly noticed it was almost 1lb heavier as the stock cam is drilled through the center. Next I decided to MIC the cam to check the lift. It was advetised as .333" lift on exhaust and intake and was actually .212". My stock cam is .228" so I threw it back in. They said they will take the cam back, but watch out, it is always a good idea to double check things like that. I almost put a worse cam in my kick. I don't know how many people have these cams in their rides???
