Hello

I dis mounting cylinder head. I use a sliding caliper to measure the length valve spring. It has 36mm (outer valve spring) and 34 mm ((inner valve spring). Service manual say :"The minimum length may not be less than
39.20 mm/1.4252 in (outer valve spring) and 36.45 mm/1.435 in (inner
valve spring). Replace the spring if it is shorter.

I have question. Is posible that my valve springs so are short ? or I have bad service manual?

apologize to my english, I little know it.
