i always pulled the exhaust manifold off with the head. if the head is cracked finding another NPI head is pretty easy. also you could consider doing the PI head swap with some PnP'd heads. the inlet manifolds are notorious for cracking because they are plastic, they usually crack around the thermostat housing or the alternator. just remember if you do pull the heads off, you can kiss those head bolts goodbye, THEY CANNOT BE REUSED.
