standard stuff for 2wd mate unless you got bigger ap's or summat but unlikely for that price.

whether it's a bargain or not depends largely on why the headgasket is leaking. if it's the usual story of being old and blown out, then you got a bargain. if it's cos the head is damaged or the block cracked then probably not, unless you can do all the work yourself and can get things like parts and machining at cost or trade prices.

i wouldn't drive it hard until you've got it sorted cos if it is only the gasket and you rag it, you could make things a whole lot worse.

anyway, hope you get it repaired and enjoy it. give it a good caning down the acle straight.
