I recall an article awhile back that stated a 10% spread is within acceptable limits for a street engine. 10% of 148 is about 15 PSI. Your difference is 23. For high performance street/strip engines, 5% was the goal. For reference, the last test I did to my 2500 mile 493 was 185-192. Thats 3.6%.
Mine idles a bit rough though. Should idle a bit rougher with the bigger cam!

If the engine does not smoke, shake or have bad street manners, run it. Enjoy it.
