12G295 Head

Just wondering if a 12G295 cylinder head should have double valve springs as standard when fitted to a 998 Cooper?

pretty sure 998 heads had double springs, 997 had single.

Ok - that's cool thanks. I'm rebuilding the 998 Cooper unit I have and the head seems to have been rebuilt sometime in it's life but only has single springs.

No. Definitely not. In period, aftermarket double valve springs were a popular line.

Sorry Lmm but you are wrong there. 998 coopers (12g295 head) definitely
did have double valve springs as standard.

According to the parts list 998 Coopers were indeed fitted with twin valve springs.

Below is an extract from the 998 Cooper section of the BMC parts list.

Items 19 & 73
