I took my head apart just the other day and i noticed there was two springs per vlave, the main valve spring and a spring inside that one, is this a stock thing or a mod? its a p90 head from an 82 turbo BTW.

Thanks

yup. the coils on the two are different. one has a higher coil rate and is also smaller than the other i believe. the inside is smaller and stiffer?

someone double check me?
