I/E ratio is poor on 516 heads, if any mopar BB head needs a bigger then usual split with more duration on the exhaust it's a 516. Also 516s pocket ported flow decent yet at .5 lift. I would relay both to Tim.
If it were mine I would look at at bullet hc273/330 on the intake. It's about 220 @ .050 and .491 lift.
With exhaust manifolds I think I would do 110 lsa. Some do a narrower Lsa to overcome exhaust manifolds flow by bringing the power in sooner, with 9.7 I think it will be more pump gas friendly at 110 then 108. Probably low 230s and less then .5 lift for the exhaust. It will be interesting to see what gets recommended. IMO [email protected] jones is a better fit at for a 9-9.3:1 383 with a stock converter and a heavy car. Probably a good cam...does not sound like a cam for 9.7:1 with a mild convertor and drag radials.
