Way back when I built my motor, Fel-Pro was the only game in town for those seals.
After hearing about all the FE rear seal leaks, and looking at the installation procedure, I decided to do something different.
I cleaned everything well and injected RTV silicone into the seal slots under enough pressure to force the sealer to fill the clearance between the main cap and block completely. The car's been on the road for 16 years and never leaked a drop yet.
The rear main cap will probably be a bear to pull if it ever needs a rebuild though. ;-)
