I just purchased a set of "Corvette" script, 7-fins valve covers for my L48, 350.
What would be the best gaskets to use. I've read that FEL-PRO gaskets are pretty good but they make so many different types. I have also read that you should replace the spark plug tube seals and grommets at the same time you replace the valve cover gaskets.

Unless you've done some extensive work on the heads of your small block, like....moving the spark plugs up to the top of the heads, you won't be needing to worry about tube seals or grommets! Tube seals/grommets are only used on overhead cam type engines, where the spark plug goes down thru the valve cover.
Any Fel Pro gasket will be fine. I prefer the thicker ones, tho, since they don't seem as susceptible to leaking. Just be sure the the surface of the head where the cover goes on is clean of all old gasket, and dry. The gaskets, whatever kind you use, will always work better when both the valve cover AND the head are dry...no oil, or any sealer. hth

And their service is great, too. I talked to the owner of the company. He has his own C2 Vette. He called to make sure I got the correct sizes for the PCV valve and breather hole. They also have their own machine shop to drill the holes. The "Corvette" script is officially GM licensed.
Thick side walls and gasket flanges that will not bend when bolts are tightened
Cast-in internal baffles
Mounting hardware included
They seem to be very high quality to me. The covers, drilling the 2 holes, the 2 grommets, and shipping cost me a total of $333. I didn't think that was too bad - especially when I saw some for as much as $500, elsewhere.
These small block Corvette valve covers have baffles cast-in as shown in image at left. These covers do not include holes for PCV, oil fill or breathers. For engines that require PCV, oil fill or breather on the valve cover, PML designed the casting to be thicker on the intake manifold side below the C where baffle is located. This area can machined with a hole. PML has a machined shop and can machine holes for $40 per hole, and holes and be either 1" or 1.22" in diameter. Please call to order if you would like PML to machine a hole for you.
Yes, the pcv valve and the breather holes are in the correct locations. For my '80 that means the pcv vale hole is in the front on the left side and the breather hole is near the fire wall on the right side. You can use either hole for the tradional oil filler hole.
