20-25PSI is actually good for an LT1, some see as lower at 15 (this is on the stock gauge). I would agree not to go to a 50W oil. Stay with what ou are using.
Switching from 5-30 to 10-30 adds nothing, once the oil is hot it the same 30W
If it's really bothering you can do a spring change on the oil pump to give you more pressure, You can do a search on this site about the GM white spring. It can be used to increase oil pressure. but that is allot of work for something I honestly don't think you need to be real concerned about.
