None that I see... 5.3 heads bump compression. Yes they have have a smaller 1.89 intake valve but I bet that is by design to avoid shrouding issues the 2.00 valve the 241 would cause on a 3mm smaller bore. BTW both have 155 exhuast valves.....More bore and I would opt for the ls1 heads but in this case 706 heads are my choice. Hell IIRC the flow is within 3-4cfm any way.....
