Carb Spacer to Solve Vaporlock - Quick Question

Ever since installing my Edelbrock 1406 on top of my LD4B, I have had hot start issues.

From the help on this website, it seems I should try a spacer first.

Do I need a 2nd carb gasket, so it goes manifold - gasket - spacer - gasket - carb? Or, will the spacer function as a gasket on its' own?

Thank you in advance-

I had the same problem. Thanks to the advice on FABO I used a Eddy 9266 and insulated the fuel lines, no more trouble!
