Yes it will be effective. There is no effect when we use any HTML tag through CSS so important of th H1 tag will be same....
You can control headline tag styles directly in css just enter h1{font:15pt/18pt Arial;} to set the font. Remember: headlines have predefined margins that might vary from browser to browser. By setting fixed margins in CSS you can reset default settings.
I'm not so sure that you can change the size of the tags. Google will certainly see that and can ban your site. Do whatever you want with headline tags but don't change their size. However if you want to change the size make sure you deny the access to your CSS file from Google robots in robots.txt This will guarantee you they will not see what you do with the headings. Anyway they don't need your CSS file.
