Dealing with hundreds of spam pages caused by a hacker

[Wardy]

A couple of my sites have recently been hacked with the hacker managing to overwrite lots of my pages with their own spam products and also adding in lots of (hundreds) pages that they have created themselves.

I have rectified this in so far as removing folders that the hacker used to over write my pages so my original pages are now back showing the correct content and also removed all the hundres of new pages that they had managed to instantly add.

I appreciate that google will find and re-crawl all my genuine pages so the correct content is being displayed and indexed for them but what is the best method for dealing with the hundreds of extra spam ages that google had managed to crawl but have now been deleted so there are loads of 404 page not founds in google?

301 redirection or contact google.

301 redirect to the home page?

Will that not be detremental when lots of the now deleted pages were for usual spammy items that have nothign to do with my site content or will google just see it as pages now gone and delete them subsequently?
