You won't find many off the shelf cams that will have the duration that you will need. You will probably have to go with a custom grind from Comp, Bullet, etc.
You will need something with around 252/254 duration @ .050". Fortunately the cam that comes with that engine (M-6250-A514) isn't overly aggressive, so you should be able to choose a hydraulic roller that will be zero maintenance, but will be able to make similar horsepower.
I use custom Comp Cams and Bullet cams with my Boss 9 engines and usually use the Xtreme Energy lobes. You're looking at around $350 for a custom hydraulic roller, plus about $385 for Morel hydraulic roller lifters. You will also need a pushrod change and possibly a valve spring change.
