    The Gen 5's will work on MK4's , check out the Comp rocker "conversion studs" to make the valve train adjustable Tom

    The water problems are with mk 4 heads on a gen 5 blocks not the other way around. Many mk 4 heads don't have enough material to succesfully seal the water passages near the lifter valley side on a gen 5 block, gm fixed that prob on the gen 6.
