My second Subaru has leaking head gaskets at around 90K. on 2004 Subaru Impreza Outback

Dealer says it is because the independent mechanic I get service at does not add the Subaru additive during a flush and fill and encouraged me to use dealer for service. I can't afford the dealer. Is there a secret additive they add during a flush and fill that a regular mechanic would not know about?

I traded first one in (1988 XT6) - current 2004 Impreza is just starting - not sure if I should try to repair or just trade again. Dealer said new head gaskets would be $2,500-$3,000. What does retorquing of heads run and is there any guarantee this would let car last another 3-4 years?
