Random afternoon update even though I just did one earlier today.
Head is off, because of my unpro camera skills you can't see the biggest difference between the 87-88 vans G64B and the 89-90 van and MM/D50 4G64, jet valves, supposedly cause turbulence in the combustion chamber boosting MPG and power? I don't know about that but they are cool looking and I haven't heard of them causing cracked heads like in the G54B.

What's left before I pull the motor the obvious stuff, starter, ground cable and some coolant lines from the trans that are bolted to the block.
