Yes it does.

I can't tell u exactly, as i would need to know what the combustion chamber volume of the head is. You need to measure this. It's a good idea to do, as you probably don't know the history of the cylinder head, and how many times its been skimmed.

It's easy enough to do. Goto the chemist and ask for an oral syrindge. These usually hold 10ml, and are accuratley graded. Lay the head perfectly level, and with the cam out or rockers slackened, see how many ml of white spirit/petrol it takes to fill the combustion chamber. Don't use pure alchold or Meths - because it evaporates too fast. To make it easier, it helps if you have a piece of glass or clear perspex with a hole in it which you can place over the combustion chamber - that way you can see when it's full.
