Changing my head gasket and while having most the motor apart I'm about to take heads off. Does anyone know if easier( or possible) to just remove the heads with the exhaust manifold attached so that I can just remove the exhaust manifold from head outside engine bay since I can't reach bottom bolts under car. I'm down to pretty much just the block on topsided engine since I was replacing intake and throttle body so I feel there is more clearance to pull attached exhaust manifold to head. Was planning on putting shortly headers on anyways so now good time to do so.
