Good info. My dad showed me that trick back when I was a tot.
A couple things to mention;
First, the surface must be clean and FLAT. Most are pretty tweaked and warped. You can do wonders with a hammer and a workbench edge. Check the flatness with a paint stirrer or ruler. The better you can get it, the better it will seal. It also helps if each bolt area is slightly higher. I like to get it straight, then go back and give each bolt hole a tap with the ball end of a ball peen hammer. this allows the bolt to clamp better. Clean all the valve cover before installing the gasket.
Second, He didn't really mention the 'wings' on the gasket (I sped thru, he may have mentioned them). They fit into slots on the edge and lock the gasket in place. Good to use pliers to make them straight too. Check the fit here before applying the RTV.

What if you use rubber gaskets? Do you have to use RTV? My old gasket was brittle cork with wayyyy too much RTV. I replaced it with a rubber gasket only, no RTV.

Good info. Cool technique using clothes pins. I'm gonna raid the womans laundry room. 
Could not agree more - Flat and Clean is key.
I find it beneficial to seal cork gaskets before installing them.
Learned about Gasgacinch in the 70's to seal my 2-stroke motocross bike engine gaskets. (76-yz125, 77-ktm250, 82-cr480, 85-atc250r, I miss them all! lol)
Been using it ever since with good luck. Works great for sealing the inside and outside edges to prevent seepage.
