@@donpegar2645 The fuel pump came from a go cart racing place they us it on Honda engines. the valve springs and aluminum flywheel are also for a Honda engine.
Dropping it down should be okay, all the bubbles from the throttle body/heater hose have to be pushed out - either back into the thermostat inlet, or out the crossover outlet. I’d keep it above the coolant crossover, but I don’t think you need to worry a ton about it being a lot higher than anything else. Just make sure you bleed out all the air
