I've never tried, but it looks like you should have room to pull the lifters out after you remove the rocker shafts, leaving the heads in place.

I've done this on a few 3400 GM v6 engines. Just unplug the fuel injector.

I don't see why not, you have to pull them before you can pull the head. Just pull the three bolts for the rocker rack.

Maybe the roller lifters are too long? Just a WAG.
