I've heard that you can grind down the welds...and it will help flow better!

i assume you mean on the header and not the head? yes, you can use a dremel to grind down the welds in the header. you probally won't notice any difference in power, but its something to do. i would not do any grinding to the head itself. porting the head can sometimes cause more problems than it can help if it isn't done professionaly.
