Help I D small block heads.

I have a pair of small block heads that I got a few years back. Had run them through the machine shop, Had 2.02 valves installed, guides ect. Just wondering how good of a head they are for just a street car. I see 360 cast in the runners under the valve covers along with ( best I can make out) is 3418915 on both . Any help would be appreciated, Thanks AL
