If the original builder took the time to choose parts that complimented each other, working together to produce the package you are about to buy, then you might want to step back for a moment and rethink changing cams.

When you get the motor out or perhaps apart for the adventure, you might just discover the internals while adequate for where you are today would be better replaced if you begin stand on the loud pedal with your contemplated modifications.

It would be very easy to see a scenario where you discover you want to replace the rods and pistons when you see what's in there. Shucks you might even want to replace some of those grade oh-so-low OEM fasteners with ARP hardware. Of course while you are in there you might decide to replace other trinkets that you discover along the way like the cast 0.010 under crank or the block that only needed one or two cylinders sleeved to get 'cherry' again - just to mention a few.

Of course you could have a well thought out purpose built engine the original builder carefully selected the components for. If that were the situation you could easily discover you have a domino effect waiting for you, that has a cascade of parts replacements recommended / needed for where you would like to go power-wise.

I think, I would try to get a build sheet from the original builder to discover what you already have. Once you know where you are, you will be much better positioned to both determine where you want to go next and how you intend to get there.
