I would go with twe they are up in canada. I have heard good things about them over cobb. Nothing bad against cobb except they take a while to get your parts to you. Worth checking out.

the coolent passages aren't off.. You just need to use sti head gaskets. If they were off I didn't notice.

Most of your power is made in the heads......that's why they are expensive.....

IC that's the way I'm gonna be going if I can find a spare set of heads cheap enough. Keep in mind that all that work will put you close in $ range to an already completed head.
