well it seems like about half the guys on here have them blocked and the other half dont. from what i understand from reading all the info is that the reason they are on there is the radiator wasnt the highest point in the cars so these kept air pockets out of the heads. if im wrong let me know. i deffinitely dont wanna melt it down because of some stupid steam holes.

Steam vents are there because the outlet of the cooling system is below any part of the head. Unlike a conventional SBC where the water outlet is in the intake manifold that connects both heads the LS engines will trap air. Air will cause hotter spots in the combustion chambers and promote detonation.
There is a reason folks like Kurt Urban sell 4 port steam vents like this...

You might want to do a little more reading on here. This subject comes up constantly. There are a fairly significant number of guys on here who have run for years with all four vents closed off. Once you get the air out the vents are no longer needed. You just need to make sure you get the air out when you do the initial fill. Plumbing in the vents is just cheap insurance against future mishaps.
I'm sure people will sell anything other people are willing to pay money for. The trick is figuring out what is needed and what isn't.
