Does this gasket kit include all the gaskets needed for an engine rebuild?

This kit includes most of the gaskets needed for top-end engine work. However, it specifically excludes oil seals, which you will need to purchase separately.

What does 'surface treatments' mean for these gaskets?

Athena applies surface treatments to help the gaskets seal better. This can compensate for minor irregularities on the engine surfaces, ensuring a more reliable seal in critical areas.

Are these gaskets made to OEM specifications?

Athena produces these gaskets following strict parameters imposed by manufacturers, aiming for a fit and seal comparable to original equipment.
