408 hyd roller, too much spring pressure?

What costs more – replacing a set of valves with associated machining costs and liners, or buying a set of springs that saves valvetrain weight and has better harmonics?

Two solutions to the same problem. Which is more economical for the man on the street?


I forgot to mention you have ZERO PROOF that anyone did nothing but swapping in a BH spring and fixing anything. Not a single link you posted did that.
