Hi!
So far you have done all but change the leads! This will help dramatically BUT if your head gasket is blown I'm afraid you'll have real difficulty in get it to run smooth as water/steam is possibly mixing with the fuel causing very poor ignition.
I did the same as you on a Golf as soon as the new leads were fitted Bingo a New Car, However there wasn't a head gasket issue.
Good Luck and A Happy New Year to you and your Family.

sealant wont help if you cracked the housing by tigting it to much it also is suppose to have either an o-ring or gasket sealant is only used very sparingly

Does it feel like its not starting from a fuel problem? I would look at the fuel filter for the 1st culprit.
