Is this LA360 XE268 cam kit deal good for my combo?

Ok. I must be stunod or something. First off, I didn't purchase my current crane cam but I thought dot to dot ( what I called straight up) was how mfg recommends installing the cam and it should perform as advertised barring any other engine mods. In the H-260-2 that would be 204/216 260/272 427/454, 112 lsa. Now don't some cams have " built in" advance? Are you saying dot to dot is 4 degrees retarded??
Second....I just bought a 3 key adjustable timing set for my magnum.
Can use on this LA. It's a double roller comp 3103. That would mean each key notch is 2 deg. It looks like I can only get 4 degrees max advance per comp. I'm at 112 and you recommended 108 so NG?? Remember, the LA is coming out summer of next year so doesn't need to be "optimal". Plus the car is most likely parked until spring.
Thanks.

Yes, but ONE MORE TIME the three keyway gear is really crap. It does not give you enough of adjustment in cases where you are "way off" and it sounds like you may be. You NEED a good billet timing set, for a couple of reasons. First, they are quality. They are not the cheap POS that's going to stretch a country mile as soon as the engine is broken in. Secondly, they will have the nine keyway crank gear so as to be able to zoom in much more accurately on the camshaft timing. I don't know how else to say it.
