Keep in mind that if the gasket and sealant  was doing its job the coolant
would not be between the gasket and the head so it would not matter what
type of coolant was there.  Now for the sludge in parts of the system and
the pitting on the outside of the cylinders or the erosion on the studs we
could have some benefits here.

Thought I would share the response I got from Evans coolant after showing
them a photo of typical Vanagon water jacket seal corrosion, and asking if
using their coolant would help:

".......we have seen this type of corrosion in steel head as well as
aluminum. The culprit is actually the acids that form over time due to the
electrolysis. Our coolant will eliminate all the corrosion factors along
with the electrolysis. Our coolant is also phosphate free."
