That's an excellent idea, Mark!!!!  I may end up trying that myself as I
have the exact same setup on my Tiger and have experienced that problem
before.

Jay,
If I remember  correctly, your car has a smaller Holley 4BBL (465 CFM?) on
top of a F4B manifold. I have also had hot start problems using a similar
setup on one of my cars. When attempting to re-start after the hot car sits
for a few minutes the engine only spins, and when it finally does start it
feels like it is loaded up or the choke is on. In my case this was caused by
the fuel boiling in the bowls, the pressure builds up and the fuel overflows
into the carb, loading up the engine. I tried heat shields and thicker
gaskets but there is no head room with the F4B so you cannot use a decent
phenolic insulator. I fixed this by installing a toggle switch under the
dash for the pump, and I shut off the pump a minute or so before I park the
car. When I come back I switch the pump back on, turn the key to prime the
carb for a couple seconds, and the car starts right up with fresh cool (ish)
fuel flowing into the bowls. The "secret" switch also makes a great theft
deterrent.

It's easy to try, there should be a connector of some type or a fuse in your
fuel pump's circuit. Get your car hot and disconnect the power to the pump
for a minute before you shut off the engine. Wait about 15 minutes then
reconnect the pump, turn the key to let it prime for a couple seconds then
see if the engine starts easily. If there is no change in its behavior then
it's probably timing/spark issues.

... I'll be back at you for hard hot starting issues later...
