Boys jeez less of the keyboard warriorness! Not everyone's a proffessional like Dumdum!

You can get refurbed heads on ebay on an exhange basis for about £300 IIRC might be worth whipping the head off and exchanging it, then doing the HG whilst youre there... It'd probably cost you about £600 in parts if you change the water pumps and tensioners at the same time
Failing that I'm sure I saw DanGTi6 had a complete '6 engine for sale...
