249 at .050 you should be running over 12:1 Static compression. Unless you intentionally went too high on your duration to drop your DCR for use with low octane fuels. At 10.5:1 static I feel you would be better suited at around 230 to 233 duration at .050. using premium unleaded. I cannot speculate lift without knowing the flow numbers of the heads. Those heads you got are a great flowing set, but after the port work, I would need to know the flow numbers at lift values to give an accurate lift suggestion. Sure you can pick an off the shelf cam, but I personally think your over cammed for your current setup and making less power than you could be. Also what’s your trap rpm? 28 inch tire and 4.30s assuming 1:1 final drive, I’m guessing your trapping somewhere around 6300 1/4 mile? I need more info...
