Google page rank + style sheet question

[david_uk]

Sorry if this is the wrong forum.

My site has been online for some years, and for some reason when I started making a style sheet I decided to call my styles by meaningful names and not the h1 h2 h3 etc convention.

I now understand that Google pays a lot of attention to the <h1>header text</h1> tags. My old style sheet system may therefore be hampering my search engine position. I'm pretty near the top, but I want to be the top.

My question is this.

Currently I'm using an external style sheet, and the paragraphs usually begin with <p align="left" class="bodytext"> or something like that. To change these references throughout the site is not too difficult a job. I can change the tags to <p align="left" class="h3"> quite easily. Thing is, will Google index my pages any better with <class="h3"> over <h3>?

To change the entire site to <h3> and then close the tag is a lot of work, whereas <p align="left" class="h3"> is an easy replacement to make, as the tag is closed by the existing </p>.

[smells so good]

will Google index my pages any better with <class="h3"> over <h3>?

My usage has been like this: <h3 class="headers"> This allows me to control the font, keeping a more uniform look to my headers, while providing good content layout for the SE's.

Here's a link [webmasterworld.com] to some discussion about this.
