Buy some Permatex Gasket maker in a tube....non-hardening formula. Cost is less than $4 bucks. Brown goopy stuff and it sticks to everything. Take the bolts out and clean them as well as the holes in the block. Rub a small amount around the bolt threads, just enough to cover the threads. Re-install the bolt and torque to specification. That should stop the leaks.
