You have your answer.
BTW thicker hg is stupid from what I gather. Read about it.
I remember a thread where corky bell chimed in on thicker headgasket idea and said it was pretty much stupid.
Seriously man, you need to search more and not create a seperate thread for every question you have.

with rudimentary, stupid questions about thick-head-gaskets, how can you know enough about tuning in general to develop the "i never believed in limits just good tunes" moniker? This is your queue to tell everyone how you did XYZ 10-years ago and how we should respect you.

A thicker HG does lower your compression regardless of application. The issue is in the quench area of the combustion chamber and piston. At TDC the outside edge, exhaust and intake sides, of the CC and piston have a near contact area that pushed the combustion into the middle of the CC causing it to tumble. This reduces risk of detonation and improves combustion efficiency. When you install a thicker HG you eliminate this effect, reducing combustion efficiency.
On the flip side, because it lowers your effective CR you are able to run more boost which can make up for that loss in combustion efficiency. I think that 2 engines with the same CR, one with a thicker HG and one with dished pistons, the one with the dished pistons will be able to either run more boost before detonation or make more power at the same boost. I have no empirical data to back up this view point however.
That said, a quick and easy way to reduce CR and run more boost is a thicker HG. A more ideal way however is installing dished pistons. In direct application to our motors, you can make enough power with stock pistons to bend/break stock rods. Therefore it is a little bit dumb to install a thick HG on a b6/bp motor in order to run even more boost/hp. If your plan is to run more boost on our motors to NEED to run a thicker HG, you will also need to install forged rods. Which in this case you would be stupid to not install dished pistons at the same time, cast or forged.
I hope that helps. I rarely feel inclined to type this much for someone I don't know.

Thicker headgaskets are for ------ ricers who don't know how to properly build or tune an engine, due to a lack of any understanding of the operational principles of said internal combustion engine. It's a dumbass bandaid idea to be utilized by morons. This is why it's so popular among the Honda community.
On the upside, I've heard people ask whether they could run two stock headgaskets to lower compression, and at least this question isn't THAT stupid.
