One of my mechanics mentioned that I should change the head gasket to a copper one which would create more compression and give more power- Does this make sense and has anyone done or recommend doing this ??

 

Thinner gasket (less than .65mm) will raise static compression. The issue with using copper is the block must be completely flat or there is a risk of leaking. The tool used to deck the block at the factory can score the surface leaving grooves. A gasket spray could be applied, but there is still a risk of compromise.

Note the impressions (lines) in this copper MINI gasket and the residue indicating blow-by.

 

The only good thing I've seen with solid copper gaskets is that you can get them in any thickness that you want. Other than that, I would not recommend them cause if your motor runs too hot (not overheating by any means) it will blow the gasket and you'll have to replace them. I had a friend that went through a few in one summer of racing.

For the labor cost of just replacing a head gasket that has not even failed you could just by a new stock gasket and put a BVH on your car and that will absolutly increase your power much more than any all copper gasket.

I am just saying since you are thinking about taking the head off and there is nothing wrong with the current gasket. If you are looking for more power why not add a nice new BVH on top of the new head gasket. (Big Valve Head)

Thats is what I told "her".
