Does any body know how difficult it is to take the head off of a 1G? And if any one has done it before, what process is involved? Cheers

Why don't you... buy a hex-headed socket to suit?

Prob the fact that the whole timing belt/harmonic balancer has to come of the motor

Well, just sell your engine, then you'll be able to afford the socket.

I really don't see what the big deal is here. It uses a hex-headed rather than usual socket, so what.
Mookie, I don't thing that one socket is going to cost you $100 Measure the distance between flats of the hexagon - that's the size.

I swear I could take off timing belts in my sleep by now. Learn from my mistake, never let a monkey who claims to be a mechanic touch your 1G. Do everything yourself, then you know its been done properly.

Pfft mechanics... only go to them if you have a holden or ford, which hasn't been made in the past 10 years.

Can the head come off without having to take the timing belt off? Also does any one know the torque settings of the head bolts on the 1G? cheers

What do you propose to have the timing belt aligned to with no head!?

It can come off without the timing belt on, but the putting it back together bit may prove difficult. Its worth taking off anyway just to give the downstaris area a once over inspection.
The Torque settings are 47 ft-lb, but there is a specified sequence of installation required to seat the gasket properly.

this is the sequence that i know of weather its the same as gt twins or not i dont know, weather its a load of shit or not i dont know, but bare with me as its a pretty complex and long process;
1, fit gasket and tension head, leave overnight and do not start the car
2,back off tension and retension (use molly lube on head bolts) start and idle car up to running, operating temp only. turn car off and leave till the next day.
3,back off tension and retension, take the car for a 10-15km drive without getting the car on boost, let the car cool down and retension
4,run the car on dyno or whatever on lowest boost, but max rpm, cool down then retension.
and after about a week of fucking around and throwing the the cam covers accross the garage from retensioning the head 50000 times the cars finally right too go
torque setting are 47flb or 64nm, and remember to tension from the center out in a circular motion.
like i said thats the sequence i know of, weather it works or not i dont know, that wat i done after blowing too head gaskets and the head gasket has stayed in tact, though i pitty #6 piston as is no longer alive, but at least the head gasket stayed in tact

Steve's method sounds good to me. Toyota don't specify a re-torque, but given past experience of modified Toyota engines (1G, 7M ETC), its a pretty good idea. Here is the tightening sequence.
