    I decided to refresh the heads on my 94 348. The large outer valve springs, p/n 148241, all measured in the range of 25-27 pounds when compressed to 34 mm. Since the spec is 39.6 +/- .89 pounds I ordered a new set from Ferrari. Well, the new springs are also low as well, 27-32 pounds. Ferrari advises this is the spring they now supply and the spec I have dated 7-1-94 has not been changed.

    Has anyone else run into problem and if so how did you solve it ?

    Thanks,

    Brewman
