I'm sure that this is asked on a regular basis but I haven't been able to find it using the search option I'm afraid.
So, when fitting a new head gasket should I grease it as advised in the Woodrow manual please?
Many thanks for any replies
Graham.

I always have and I'm pretty sure it's done no harm. I like to think it helps the gasket settle down evenly under tightening and provides a token barrier against water seepage when the engine is first filled.

Graham,  I have grease on copper/asbestos head gaskets for about 40 years it does work. Soak the gasket in water over night. I have not tried with modern gaskets, may be someone will report if it works with the modern replacements.

How well have you found the modern non asbestos gaskets seal around waterways? Maybe its just me but I have noticed a tendency for them to leak, something which appears to be a relatively new phenomenon, I now use Hylomar spray to prevent this.

Greasing was a common recommendation in the 1960s and I always have. However did not seem appropriate for varnish coated gaskets as many were.
The main thing is that the grease is the merest film. I have had engines apart where thick grease has formed indents in the gasket!

Many thanks for all your replies.
I will certainly use a smear on both sides on re-assembly.
Ruairidh, may I ask if you use copperslip for ease of removing the head 
at a later date or for some other reason please?

Hi Graham,

I use it to help with future removal - I apply it to the studs (not on the threads) for the same reason. Hope this helps.

Excellent call, I will definitely do the studs.
Many thanks again.
