do *NOT* take out your private grievances in a public forum - it's totally unfair to the seller (who in most cases hasn't even been called to ask about it in person), especially when you're up against a forum sponsor who, from the vast majority of buyers, has had nothing but good things said about him.
If you dont wanna wait, ask for a refund (like I did when the delivery date blew out), and go pay more somewhere else for a faster deliver.
The headgasket has been sent from Japan direct to your house. Like draven said, if you dont want it, just ask for a refund. Draven did, and got a refund straight away.
