Springs ibiza bocanegra

Good afternoon,

I have a seat ibiza bocanegra 1.4 180hp, and I have doubts in the springs of the valves, I have two types of springs one bigger than the others. My doubt is what the springs for the intake and exhaust part.

Thank you

It's not an engine I'm personally familiar with and this isn't something you want to get wrong. Typically you require a higher spring pressure on the inlet valve than the exhaust as the valve is heavier and hence harder to control, and also the inlet cam profile usually provides more lift. I'd personally suggest you find a workshop manual for the engine and confirm the spring location.
