If all of your connections are good, and all grounds are correct you don't need a larger fuse block. If any of the grounds are missing or bad they can cause all sorts of electrical problems. It will try to find ground anyway it can causing overloaded supply wiring. Check voltage drop through all connections.

If you up the amperage you can overload the original wiring. After you get it sorted and it will not blow regular fuses call Ray and get the fuse links. You can also find fuse wire at some parts or electronic stores. You can then make your own. Putting a penny in the fuse holder works until the house burns down.

But what im getting at is that a FB, more importantly a GSL-SE, alternator is putting out 50~70 amps (right?). By using a 10amp (which blew), 20 amp(which blew), and a 40amp(which blew) size fuse its safe to say that the alternators current was blowing the too small fuses. So in practice a 60~80 amp fuse works fine, which I suggested which nobody else has, other than use another fusible link.

I dont know that it is about fusible links that I personally dont like, but a fuse is easier to source, buy, install, and check if blown than one of those links. Sure others may see the stock fusible link block as fine, but for others where the block disintigrates from heat and age the FC block is perfectly adaptable to make a secure location for new fuses, and you can then add a fuse for another accessory since the FB would only use 5 of the 6 available slots.
