Bore / stroke 66 x 72mm

72 mm stroke, so the difference in bore diameter is 1.5 mm. 72 x 1.5 = 108 cubic Millimetres. Divide by 10 to make it cubic centimetres and the answer is 10.8. Your new engine will be 256.8 cc.

To be honest for the work involved it would be easier to just swap out the 1600cc engine for a complete 1800cc engine. Engine cc can be set by different things. Piston bore, piston stroke, connecting rod length and so on. 1800cc pistons might simply be the wrong size for the cylinder bore.

Visit two-stroke engine a four stroke one cylinder to cylinder four cylinders if you need to measure the borer and the bike is a part just use calipers or just look it up online

If the engine has a bore and stroke that are equal to each other is a square engine. An engine with a smaller bore than the engines stroke is undersquare. Engines with a larger bore then stroke are oversquare. If your engine is square the valves will be ok.
