There is no need for capitals, your questions will be attended to as soon as possible.
It is not recommended a head be welded if there is indeed a crack, depending on your financial situation. M20 and M30 have a slightly different head from memory, contact your nearest wrecking yard. Once a used head is acquired, have it pressure checked, valve stems check and seal replaced, decked is necessary.
