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 have one that needs to be changed but theres a guy on the ranger forum that says he tried and the head has to be removed.at this point im leaning toward leaving this a five cylinder.no way am i removing the head.it was hard enough removing the valve cover.

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