engine swap

What is your question?

Can I replace the engine from a 1994 Nissan Hardbody with an engine from a 1986 Nissan Hardbody. Both are Z24 engines with Automatic Transmissions and the only difference is that the '94 is an extended cab and the '86 is a standard cab. The '86 engine runs, but the '94 has a blown head gasket. Will the transmissions bolt up with out a problem?
