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

the H-260-2 that would be 204/216 260/272 427/454, 112 lsa.

The .050 timing specs for the Crane H-260-2 show it as a 112, installed at 107........ so “in theory”, it should have 5* advance ground into it.

5* advance is pretty standard fare for a lot of Crane grinds.
