When changing head gaskets on a 1989 L98 (aluminum heads), can you just unbolt the heads with the complete valve trains in place, remove old gaskets, install new gaskets, and torque the heads back down? The reason I ask is that the steps I've read talk about lash adjustment. Just not sure if the installed valve trains mess up the proper torqing of the heads on reinstall. If you can keep the valve trains inplace, can valve seals be replaced without removing rocker arms and getting into lash adjustments? Thanks in advance. I'm scoping out a winter project, and trying to avoid getting involved in too much engine internals. Thanks in advance.
