250hp is what a stock 350 will dyno at with headers. 300hp is pretty easy with a good cam [read: not generic old ass tech that everyone keeps using for who knows what reason, which is basically anything melling or the flat tappets GM puts in its crate engines for some weird reason]
If the currents heads need any machine work, they aren't worth the time. If its just new seals then sure go ahead and run them.
