They should come with the paperwork. If not megacycle has them posted on thier Pdf catalog. It's the very last page.
PCW has ""some" info posted for thiers as well, although lobe center info isn't listed.
If you cant find what you need I can scan my slip and send it to you.
For the most part I'm guessing PCW gets thier cams from Megacycle, although perhaps some of PCW's grinds are PCW custom grinds because the two websites don't match exactly.
PCW's 03, 05, 06, 07 Cams are not on Megacycle's site, But the 01, 02, and 04 cams are listed on Megacycles site but use a different part number than the format PCW uses.
But my 03 cams did come in a Megacycle package.
Sean could probably clear this up.
I got mine from Megacycle, through Sean, and got a better price on them that way (even with Sean getting a cut) than buying them direct from Megacycle. One of the four had some PCW markings and part #'s on it so I think these cores must get around a little bit.
I checked them and the base circle, lobe length and lift all measured out the same at least. I wouldn't have a clue how to check the duraction and separation angles with loose cams.
