405 head valve washer size

Maximus

Looking at buying valve washers for upgraded klracing valve springs.

they sell valve washers in “large” or “small” size.

does a 1981 405 head come with large or small washers, or will I have to measure to be sure?

https://shop.klracing.se/sv/artiklar/enkel-ventilfjader-volvo-8v-39kg.html is the valve spring

and

are the washers

KL Racing say in the description they use the standard spring washer with the spring you've selected. The washer is really just there to stop the spring from pounding against the soft aluminium of the head casting, which would quickly damage it.
