Valve Tip/Rocker Height Question??

I've read a lot about Mopar small block valves tips needing to be the same height after assembly. Does it does it really matter if they are the same height if you use adjustable rockers?? I recently (one year ago) had a set of 302 castings completely redone at the machine shop and installed them on my stock 318. I wasn't a FABO member so I didn't know anything about the valve heights so I never bothered to ask the machinist nor did I check the heads after overhaul. I'm not even sure if I put the rockers on correctly. But the car runs pretty good although I thought I would get a little more power out of the mildly ported 302s. The engine currently has non adjustable rockers on the original '69 motor. I bought a set of adjustable rockers and I'm wondering it would help if I swapped out the rockers since the valves may not all be the same height??? I bought the adjustable rockers for the 318/390 stroker I plan to build but until I finish the 390 I wanted to see if I could improve the 318 for now. Will the adjustable rockers compensate for the valves NOT being the same height???
