Yes my crank gear has 3 keyways. A - 0 - R. So If I put it on the "A" on the key on the crank , then just line the Other "A" to the Cam gear ? and that's 4* Advance
Maybe, maybe not. It depends on whether or not "everything" is machined to the same tolerances. That's the whole purpose of degreeing a camshaft. To overcome machining differences in timing sets and camshafts. When you are discussing timing in degrees, there's room for error, especially when mixing and matching different brands and a lot of times with the same brand. Unless you degree it, you have literally NO idea "where" the camshaft is installed in the engine.
