You can get a stroker kit but they aren't cheap and it's a bit of work. You can bore a 2V but the most you can safely go is about 0.020" over--this due to the thin water jackets between cylinders.
If you must touch the bottom end and if you really want to up the displacement, don't bore anything. Just get a stroker kit, balance/blueprint the crank; pistons and align/hone the cylinder bores.
Again, not cheap to do if you want it done right. Plus you have to upgrade the top end; fuel delivery etc etc to get the most out of it. The benefits will net great gains but for the $$ outlay you'd be better off starting with a 4V....good luck either way.
