That is exactly the point, "YOU DIDN'T KNOW", but you offered advice anyway. And if others had not stated otherwise the OP would have been misled. People, please if you offer advice, and you are not sure, at least state so. That way it is not taken as gospel.

"Not really sure about a slant six, but roller cams seem to work on other engines. You might want to check on that."

Guess what there is a roller cam for a slant 6 that's what matters! Be it race or street is a different matter, that being said as long a core can be acquired you can get a custom grind on it for the best performance. With that said are you telling me that a standard cam, is more efficient then a roller cam.
