Chris, you might have kinger's guy deck the heads a little more than usual to bump your compression too since this will be an N/A car.

Custom pistons are a better way of doing it though as valve to piston clearance is already a bit tight on our engines. You can always fly cut the stock pistons, but then you're getting into more custom machine work and weakening the stock pistons further by cutting them. Chris, at least finish any cam specs before building or modifying pistons as you may have to have them fly cut anyway to clear any higher lift cams or increase in duration.
My vote = open up the chambers to lower compression and unshroud the larger valves, then get larger domed custom pistons to raise the cr back up to 13 or 14:1. Siamese the intake runners, from the last curve of the UIM, through the LIM, to about 50mm or so into the head ports. Ditch the secondaries and guide bars. Long tube, tuned length headers are a must.
