Head Gasket

Ok so I have a dilemma. I am in need of a good head gasket and keep coming up with nothing.

I have my block bored .040 over (88mm bore) with forged pistons. I'm shooting for around 700-800HP. No problem with my set up and I have all the supporting mods. No for the question...

I hear stock head gaskets are great and I agree but they are for an 87.1mm bore and I have a 88mm bore. In addition I am running high horsepower. Cometic is out of the question. I have hear too many nightmare stories with those head gaskets and even hearing some people drilling the rivets out because they would t allow the head to seal properly. So no go on those.

Are there any gaskets out there that are good that wont kill me in the wallet? Do they make an 88mm bore stock HG? Anyone have experience with Tomei or Greddy HG's? FYI the heads are machines straight and I am debating whether or not doing the same to the block. It's cast iron so I can't see it being too far out.

Let me know some suggestions. Please no commentary. Just looking for cold hard facts and hard personal experience not opinions.
