Html how to make H1, H2, etc as links?

Question

What is the correct code for turning a h1, h2 etc heading into a link and search engines index texts of header and link both?

Is it:

Answer 1

If You go with code1

heading

you are just able to make it as a link with highlight feature. But If you go with code2

heading

you will probably able to satisfy some css property as h1 a{ //hover or text decoration}

I will go with second code. ... Both will work.
