It says in that link that they are larger in diameter and length than regular springs.

These diameter springs are generally based on the nominal 1.4375" size,
and some spring pockets are machined to 1.45",
but what ever you are planning,
make sure your valve length and cylinder head can allow this machining,
and I personally would do the machining once I had the springs in my hands,
so that the fit can be nice.

What's wrong with CB650/VW650 springs?

[tezer]

Nothing wrong about vw 650 spring,
but the plan is to have them on a type4 head and then you have to weld the spring pockets
because the vw650 spring is smaller in diameter or you have to yo use a valve spring cup
so i was thinking to se if this would fit straight in whit out Anny additional work
