Coolant

Good day everyone,

I'm replacing a heater core on my 69 f-body project. I have aluminum heads, intake and radiator and just realized that the heater core is copper. Curious to hear recommendations for coolant type with a mix of these metal types.

I'm trying to take in a lot of technical information but I haven't seen anything that directly addresses this question but I think HOAT looks like it might work.

I appreciate your recommendations.
