Has my engine just taken a sh*t??

But it yeah I don’t think the pressure idea is a good one as it would probably be easy to overcome while fiddling with the springs and then bye bye valve.
Bumping the car over until you get the piston you want to work on up to the top isn’t an awful idea though is it?

I didn’t mean remove the plugs hehe, I meant just disable the ignition. Should have been clearer there.

You could just use rubber bands to hold the valves up. tedious but it would work. Use smaller rubber bands wrapped around and around again on the valve stem. Should be sufficient enough to keep the valves from dropping.
But if you are replacing the lifters the heads have to come off anyway and it is a mute point.

Hey, that's an idea... or maybe a fat o-ring that has an inner dimension that is very snug to the valve stem.

Yeah, it would be a challenge. I think the rubber bands could be cut, wrapped and tied. Have to think more about the o-rings... maybe not possible unless you are Houdini. In any case it would be a PITA.
Forgive me for not understanding, but how are you gonna get it around the valve to begin with? The main time this is a concern is when you are pressing the springs down to remove the retainers. There is not enough of the valve tip to put anything around and you sure around gonna get it around the valve with the spring and retainer in the way..

Noob question: do the exhaust manifolds need to be unbolted to get the heads out?
Also, is there much involved with disconnecting the fuel
system that runs over the top?

Is pulling the heads do-able as a 1 person job without a hoist? I have no idea how heavy or awkward the heads are.

If you’ve never done anything like this before, I recommend not popping your cherry on a $70,000 vehicle. It could cost a lost to learn a few lessons!

You don't need a hoist, heads are heavy but manageable by one. Yes, exhaust manifolds need to be disconnected, part of what makes the job such a PITA. Also need to drain coolant. Fun, fun, fun.

Coolant draining is no problem really. Will all the accessories need to come off the front of the engine too? That would definitely have me biting off more than I could chew.
I’m going to have a go at cranking the engine over tomorrow and get a camera into the spark plug holes to see how easy/hard it is to get the piston where I want it. If it’s easy then I may consider doing the springs, if not then I’ll let a pro do it instead.
I assume the piston won’t travel higher than the spark plug hole? So when it’s near the hole we can assume that the valves won’t fall far enough in to get lost?

Only stuff has to come off is attached to the head or in the way.
You don't want to visualize piston position with a camera. Get the firing order and put the timing mark so #1 is TDC. Then work from there. Gonna be hard to do bumping the starter. Much easier if you can get a socket on the pulley and turn by hand. There might be some other way to do it but I don't know. If you must do it with the starter maybe try one of those remote starter tools to turn it over whilst you watch the timing mark.

Remote starter is a good idea though. It'll soon get old having to run into the car and press the clutch in every time I want to crank the car over.

From what I remember when installing the Procharger, getting to the crank bolt is a royal PITA. The steering rack has to be unbolted and from what I remember the subframe loosened and dropped a few centimetres.
