supra head gasket questions+ rebuild

[Bill UK]

No one touches the Supra except myself, I've set the timing dozens of times using # 6 as stated in document below. (# 6 is at the back) if you have a variable setting on your strobe light set it at zero. It sounds if you may have a doggie HT lead. Does the timing advance when you remove the terminal link in the diagnosis box.

Also make sure the arrow on the pick up clip that connects to # 6 HT lead, is pointing towards the spark plug.

I have a 91 turbo and tried once to replace the cylinder head gasket. I removed the turbo charger, intake system. removed the 14 head cylinder 10mm bolts, but the head won't come off. Used a rubber hammer to bam it from the side, but won't help. Finally, I put them all back.
Can someone tell me how to remove the head safely?

Well..., the guide pins are working then. Since you're smacking it about from side to side.

You take it lose..., sounds like you have.
Means you have already locked yourself into machining it again.

Chuh..., You need to start your own thread so we can help you so bill can work in peace to get andy up and running.

And when you open your own thread. ELABORATE...., on and in. Detail.

Help us help you.

Well Andy’s up and running again, I dare say Andy will explain the initial problem (How the hell you can fit the head up side down I don’t know) One thing I did learn from him which I didn’t realise before is that when # 1 sparks so does # 6. The 7M-GTE engine has bank of three coils, the coil on the left connects to leads 1 & 6 the middle coil connects to 3 & 4 and the right hand coil connects to 2 & 5. When # 1 sparks so does # 6, but # 6 is a wasted spark and does nothing. The same applies to the other coils they spark in pairs but one of them will be a wasted spark. Toyota in there wisdom referred to # 6 for the strobe pick up, this saves removing the coil cover that obscures # 1 lead; as they both spark together, it all makes sense now. Firing order just in case someone needs it 1-5-3-6-2-4

Those coil packs don't look fun to me.
They look more pricey than the standard dist cap and rotor.
Plugs and wires cost the same.

What's the life expectantsy of a new oem set of those and what do they run, american if you please.?
