What year? Check that your crankcase ventilation hoses are all connected 
and not blocked. Has this engine by any chance been rebuilt using the 
cheap drop-in oversize pistons/cyls? If so, the solution is probably to go 
back to std 85.5 P/Cs.

The heat soak after shutdown is boiling off the gas in your fuel lines. Their 
may be a small leak that allows air to get back in the lines after things cool 
back down. The easy solution is to just turn the key from OFF to ON several 
times, each time letting the fuel pump run for its ~1 sec. This will prefill the 
lines without running the starter.

It's not a valve. You might watch the fuel pressure after you shut down the 
engine. If it drops all the way to zero, then the check valve in the pump is not 
working and this will make the heat soak problem worse.
