Did you try flushing the heater core? According to shobox.com, a clog in this system is the #1 cause for a no heat complaint on a 4th gen f-body http://shbox.com/1/4th_gen_tech2.html#heaterflush.
1) Remove the heater hoses at the water pump. This allows flushing of the hoses and the core.
2) Orient the hoses to keep all moisture off the optispark.
3) Using a garden hose, flush into one heater hose allowing the water to come out the other.
4) Do not use high pressure. The cooling system is only rated for 18 psi. Full hose pressure can be over 50 psi.
5) When the water looks clear, swap hoses, flushing into the other one.
6) Reverse a couple of times to help ensure a good flush.
7) Re-connect the hoses and refill/bleed the system.
