Hello, we are in the middle of repairing the heads from overheating. We are in need of valve springs for 25000 Mark II Diesel heads. Having a difficult time finding them online or if someone has another brand that would match the specs, that would be great. Please respond asap as we need to get it up and running right away.

Thank you.

I was told this could be a cross reference part that might work too.
