Is there anything special to do to prep new intake manifold gaskets? Do they need to be oiled or anything or just pulled from new box and laid on the heads and torque intake down per specs?

Gotta replace my knock sensors. I have all the parts... Looks fairly simple, just a lot of things to remove. But I am replacing gaskets while I am doing the job.

Thanks.

no oil. clean the surfaces on the head and manifold that the gaskets touch.
remove the intake with the injectors still on the manifold.
