So how will these cams differ? 229/244 .618/.610 LSA112+4 Street heat #2
229/244 .615/.596 LSA112 Custom grind
So with the difference in Intake, Exhaust and LSA
is it basically a street heat cam that is a little more mild?

What are the flow numbers of the heads? Heads that flow really well, especially past the .600 lift mark would benefit from the higher intake/exhaust lift cam. The one with 112+4 LSA will theoretically have a lower power band than the straight up 112 LSA cam, but to be honest, there is really not much difference at all between those cams. Also, the cam with the straight up 112 LSA can be advanced or retarded.
Advance
begins intake event sooner
opens intake valve sooner
builds more low-end torque
decreases piston-to-intake-valve clearance
increases piston-to-exhaust-valve clearance
Retard
delays intake event
opens intake valve later
builds more high-end power
increases piston-to-intake-valve clearance
decreases piston-to-exhaust-valve clearance
Advance
