Change alignment of H1 on a single page

Hi

I wish to change the alignment of one of the H1 titles.
Why:
I developed a Hebrew(RTL) website, but added a single English page (about us), only there I want to align the title to the left.

I tried:
h1.page-id-14 { text-align: right !important;}
(lets say that the page ID is 14)

Please advise
Guy
