leaking 904/999

i have tried all types of gaskets with out sealer,,even a leather type gasket,, the new style from mopar,,if i spray on adhesive and it doesnt leak,,its been off so many times i wont want to take it off again,,,if it does leak i may spring for the thick aluminum pan,,,but its to costly for a street rod,,in my opinion,,but some times you got to do what you got to do,,

thanks every one for your input,,,,
