I had to do it on mine once(wide open on bottle down I4 lol)

I did not remove the intake, i just dropped the exhaust manifold then zip tied gears to the chain. removed the head, one side at a time. place in new one the same way(get the copper head gasket spray total life saver) reassemble and turn it over by hand and make sure the cams are on point. copper rtv ftw.
