I would use the 2.5L NA HG's with the latest PN for the 99 Forester. They should be a multilayer HG.

$100 a set from the Cometic site. Is this a decent deal? I'm in the middle of a HG replacement and was going to use the Felpro HG kit from Autozone.

Go with something like Cosworth (or OE). Some people around here really don't like cometic head gaskets.

I would use the oem Thick DOHC gaskets if I were you. That puts your CR around 11.5:1. You can grab a set on ebay for cheap. If you use the sohc gaskets your CR will be very high.
