yes you will get more HP...

but remember to run higher octane....

you don't want the case of the knocks...

you will gain a SMALL amount of hp because for every .010 you deduct from your head gasket (which equals approx 1 layer) your compression will increase by only .2

Example: If you had a stock engine running 10.0:1 using a stock 3 layer headgasket (.030 thick) and you used a 2 layer headgasket (.020) in there, your compression would increase to 10.2:1

I doubt you'd even be able to feel the slight difference in power a change like that would make. Higher octane fuel wouldn't be required for a small change like this.
