best oil to break engine in???

[ocbaud]

what is the best conventional oil to break in an engine?
i heard that earlier this year, the government made all the oil manufaturers remove something from most of their oil products. i forgot what it was called, but its supposed to be good for breaking in non-roller engines.

i've heard that some off-road and race only oils still have it in there. anyone heard about this?

also, is there anything special i need to do for my dip stick before i put it in. its just a normal chrome stick, but will it read right since i have a 7 quart pan???

also, should i use sealant on my valve covers? the covers when they are bolted down look to be sealing really well.
