Yes, it is totally streetable, nice idle with a burble. It ended up with 8.6 to 1 compression ratio and the 197 HO heads measured 108.0 cc's across all 8 chambers(!). A 2801 is very similar to the factory 068 cam, so very docile. I think the 2802 is leaving power on the table, as are the factory RA manifolds with their tiny outlets. Hopefully you have the repro RA Restoration 'enhanced' versions with the 2.5" outlets. Definitely run the Pypes 2.5" mandrel headpipes on either manifold as that first bend to the back robs a ton of horsepower if it's not mandrel bent and at least 2.5"!
