LA 360 roller engine ?

I got a chance to buy a good running 91 360 tbi engine which i believe is a roller la engine. I'd like something to throw in my car for now to play around with until winter gets here. Heard engine run and it sounds good however before install I'd like to at least throw a cam in it. Prefer to grab an off the shelf one and run it. I see some cams for a a magnum or a retro fit cam. Im assuming I need a retro fit cam. Also what sort of compression are these engines and are the heads decent or do I need to replace. Im not wanting to get to much money into right now. Be nice if I could use the stock rockers as well. Definitely would like a nice sounding cam that will perform decent. Or would I be better off with a magnum engine to start.
