Stripping head, more engine questions :)

You talking the silver fire seals or the copper injector seals?

Ideally you'd get them out with some picks

But tapping with a small screwdriver and tap them gently with a hammer to loosen them if they're stuck.

Easier to see what you're doing if you get a torch in there too.

The copper washers can be a bit of a bugger, but tapping them round gently with a screwdriver until they break loose is the way. You may have to tap away to bend them, almost cut them in half if they're that seized in.

Again, be careful to try and not damage the the ali under them. The copper is pretty soft and you can end up marking the injector seat underneath.

You can get the injector seats cut again if you do mangle them. You may have to run slightly thicker copper washers to compensate though if you do.

Is the head thats off the car? If so, any bits do fall down the hole, you can blow them through with an airline and they'll come out through the precup holes.
