If your looking for a pure fun street car, Id say go for it. Id personally go a little bit bigger, (22X/22X ~113+4? <.600") Regardless, Your cam will have good street manners. Id put a bit more converter in it, throw in a 2800 or a 3200 (MAX) and cooling for tranny. Replace rear main gasket since your there anyways. Good tires and a tune, (careful with that 10 bolt and DS) and other than the tranny (which may never give you troubles) you will be good to go. As far as what its capable of, we could only make educated assumption. It should be torquey for sure but its fairly mild, wont make impressive dyno numbers (as if it matters) or impressive quarter mile times, but for a street car it will be plenty to take on the newer 5.0s and Camaros. Probably beat them easily. Could even get a set of 799s on ebay for 600 bucks completely rebuilt, swap springs over, coil pack mounts, gaskets, bolts, valve covers, bolts and grommets, (GM has a Head rebuild kit, summit or jegs) might run you ~$750 for more compression and more bottom end - mid range torque. Or if your okay without a car for an undefined amount of time, send what's on them out for porting to AI or someone reputable.
Edit: You have 99 Heads, you can reuse center bolt valve covers, bolts and grommets.
