Joe,
If you are using the standard dual piston master cylinder you can INCREASE
rear bias by going to a stiffer spring between the forward piston and the rear
spring. We had to do this on my TR6 to get more rear bias without going to a
dual cylinder. However if you are using the single piston early master
cylinder Henry is right, you cannot add rear brake, only remove front. The
effect may be the same in the end, but you will significantly increase pedal
pressure by adding the valve on the front brakes.

I assume you are using a dual circuit master brake cylinder. Obviously, no
adjustment here.
You could convert to a dual master cylinder setup. Maximum adjustability
using a bias bar. Spend your cash once, can play with brake bias until the
cows come home.
You could install a proportioning valve in the brake lines. You will not be
able to ADD any rear bias, but I assume you could put the valve on the
FRONT brake circuit and crank that down a bit. I don't know if I would go
that route.
That leaves playing with the size of the rear wheel cylinders, using a
better brake lining on the shoes, increasing the size of the drums, or
converting to rear disk.
What did I miss???
