Old seadoo 560 engine head gasket

[gkm24]

I have had my engine rebored and a new crank etc. I am just about to put the head on and wondered if I need to use any sealant on the cylinder head O rings or just bolt the head on and torque it up.
Any advice greatly appreciated. Thanks.

Nope. just put them on dry, and bolt it together.
