I will disagree about which side to put a thin paper gasket. I would put it between the bathtub gasket & the head, reduce the chance of oil being sucked into the intake ports.
You do it your way, I use Hylamar to seal around the ports with the bathtub gasket , no leaky.
Don't you think it be better to have the paper gasket between the aluminum and metal, Ma Mopar thought it was a good idea with the sixpack aluminum intake. look it up.
