As my seepage is only near the firewall end of each head, as obviously from oil tracking streams on the head,,,for now as an experiment, I have slathered a dose of black Permatex silicone on the head side of each Superperformance gasket at firewall end,,,,about 8 Inchs from the end of the head.

I do have an inch pounds torqometer meter snapon torque wrench,,,picked up many years ago on EBay.



Maybe try some threebond, you can buy it from a mazda dealer R2Y110431. Best sealant i've ever seen, wipe the surfaces down with lacquer thinner first to get the oil off. Its the only thing that will seal a rotary oil pan, and you need a mallet to break it free later on.
