vapor lock

I have a Pro Street Duster /440 edelbrock single plane and edelbrock heads.I have a wood spacer, changed the intake gaskets and had the intake ceramic coated. The problem is when I have driven the car for a while and cut it off and try to restart it without it cooling off it won't start. If I spray the maifold with water it will start in 10-15 mins or raise hood and let it cool down.
