dont worry about the head gasket they really arent that bad to do - they cant be cos i did mine and 12 months later its still going fine !
you will need : a good tool selection ,i got the halfords advanced set for £120 and it had pretty much everything i needed bar a torque wrench .
head gasket set inc head bolts
oil and filter
coolant (red)
water pump
timing belt kit
decent engineer to skim the head .
obviously there may be other peripherals you need depending on the state of things as you remove them .
viewtopic.php?f=16&t=50758heres the link to the thread when i did mine . i think mine cost less than £400 including the tool set and the head skim.
where abouts in the wirral are you ?
