you don't need a gasket between the intake mani and the head. if your mani is cut flat, just a little bit of high temp copper snot and you will never have a problem. i learned that from Dana of Dana's autosport in N.H. He raced a bunch of 8v rabbits in the 90's and had a shop in Heniker, iirc. i used his advice on my 32/36 carbed motor and never had a problem. again, i had that mani cut too.
