I'll buy both but have a couple questions.
What coolant was used?
I assume you have all the mounting hardware for both blocks?
You will vouch that at least looking in the inlets you see no "goop", algae, sludge, residue, corrosion, etc?
Block surface is undamaged (no nicks, cracks, gouges, etc)? Some oxidation is no problem I got copper cleaner.
Answer the above and give me a quote for both including shipping.
All mounting screws, rubber washers, nut are included for each card.
Blocks were run by alexmat I have not run them so coolant used is unknown. They have been cleaned and flushed with warranty sticker untouched.
