ive ran into that a number of times. i have always just taken some 100 grit paper on a block and scuffed the mating surfaces real good, put a thin layer of high temp permatex around the water passages on the head , install the gaskets, then another thin layer on the intake side, and torque it down. ive never had one leak on me. unless it is real bad , you should be fine...my $0.02
