Accessible site - hidden H tags

[dalecoms]

I am building a site using css for layout, Id like to include H tags for reasons of sematics - so it will make sense for people using screen readers. I dont require the H tags to show when using a normal web browser so Im considering using the display:none property.
Will google penalize me for this? Im not using them for SEO - just to provide better markup for visually impaired users.

Thanks for any advice

And what's with the rest? No markup for them?

As far as i know display:none will not do any good for screen readers, only visibility:hidden does.
