Default 1.8 L heads on a 2.2L block

I found this ebay auction for a guy selling a complete 1.8L motor... http://cgi.ebay.com/ebaymotors/ws/eB...982978818&rd=1

would there be any gains to putting the heads from that 1.8L motor on my 2.2L engine?

Guys have been talking about doing this hybrid, but having measured the Ej18 combustion chamber, I am wary that there is much gain in CR at all. A better hybrid is to swap out your 2.2l bottom end with an EJ25 shortblock. More displacement and more compression at the same time...

Either that or buy this 1.8 and turbo the crap out of it.

Would you like to point me in the direction of the people also doing this hybrid as it might be a very real possiblity for me.
