When checking volume on cylinder heads, I like to use windshield washer fluid as the measuring liquid. To keep it from flash rusting seats and iron heads after it’s drained, I’ll put a splash of radiator coolant additive in the gallon jug. This has corrosion inhibitors that will stop the rust. Water Wetter works great for this. I also use it in any water based cutting fluid for many other operations as well. Another great use is to add it to your bubble spray for pressure testing blocks and heads.
