I agree, they are a Chevy dealership so everything should be good to go. I just wouldn't buy from any billy bob selling engines on Ebay. If for some reason you should have a problem it's best to be dealing with a reputable company.
The center bolt valve covers were an improvement over the old style and a good improvement if you ask me. The adapters are just creating more places for the covers to leak. I'm as old school as anyone but since I installed my motor there is no way I would go back to the old perimeter style covers.
If you want more HP just install a good intake and 4 barrel carburetor with long tube headers and 2 1/2 inch exhaust. You can also install a MSD ignition system. All this will help the motor to breathe and the extra spark doesn't hurt. This is how I have mine set up and it has a lot of power.
You can also add 1.6 rockers on the intake side. I started to do this but learned I might have to drill out the holes for the push rods so I decided not to mess with it. I didn't want to pull the heads or take a chance of getting metal in my motor.
