I must be way off here, but that comp cam has 110 LSA and cannot be changed unless reground. It has 106 intake CL so this = 114 exhaust? Centerline, any amount of advance or retard still comes back to 110 LSA ?

There seems merit in a 105 LSA with your 4040 weight http://speedtalk.com/forum/viewtopic.php?f=1&t=938
Maybe a custom cam grind to suit your combination
