Yes the 333's will fit the build just fine.I'd suggest bigger valves[2.06 i.,172ex.]bowl work with port match[nothing crazy],and Edelbrock Performer RPM single 4 bbl.intake,a Show Cars 0950 hyd.flat tappet cam,and a carb in the 600-650 cfm range[Thunder AVS-2 or Holley 625 Street Demon]Use a 3.25-3.50 gear.Headers will have to hand made,and you'll need an oil pan made for the swap.As to pistons,these parts are CR rated for a ca block.A good choice would be the KB Icon pn 7819[plus oversize] and an aftermarket 6.385 rod.This will get you to between 10-10.3 CR.Perfect for pump gas,and the low-mid range torque will get your attention in a hurry.
