73 340 SB Rebuild, Need Help Selecting Parts

Hi mate, looks like a top combo going on there. I'm doing something very similar to have fast fun family car - the wagon in my picture.

318 heads with 2.02/1.6 valves, ported and decked.
360 block @ .040" over,
KB107 pistons,
Scat cast crank & stock rods,
Crower 31243 cam with .480/.503 @ 227/237 (@.050")
Speedpro hydraulic lifters & stock pushrods,
Rochester Quadrajet & ported Crosswind manifold.

The static compression works out at about 11:1 with the decked heads so it will need a strict diet of 93 (98RON, readily available here).

If I had to go again I'd probably choose a milder, more modern camshaft grind but this one was only $50 so I couldn't pass it up. Either way it'll be a bit of a screamer once it gets going and still have buckets of torque in the good usable 2500~3500rpm range.

The big spreadbore will help up top and down low but might hurt a tad in transition through the midrange.
