Not 100% sure... I think on the 3800 Series one engines the springs are 105-110Lb springs... But maybe a better spring for the increase in lift would be a decent idea?
I think we are .250 intake and .255 exahust for the cam... So totall lift with 1.8'* would be...
.450 Intake and .459 Exahust... Hmmm seems interesting to me as well, especially if they work with no issues on the LN3 heads....
