What does 'no retorque design' mean for this head gasket set?

The 'no retorque design' means that once the head bolts are torqued to specification, you do not need to go back and re-torque them after the engine has run for a period. This is due to the steel core construction which helps maintain gasket tension.

Why is it important that these gaskets are designed for imperfect sealing surfaces?

Engine blocks and cylinder heads can sometimes have minor imperfections or scratches from previous use or machining. Gaskets designed for these surfaces, like these Fel-Pro PermaTorque sets, use special materials and coatings to effectively seal these small flaws, ensuring a leak-free engine.

What is the purpose of the anti-friction coating on the gasket?

The non-stick anti-friction coating on the gasket helps it slide into place easily during installation without sticking to the sealing surfaces. It also aids in sealing small scratches and imperfections on the cylinder head or block, contributing to a more robust seal.
