“Super stiff. Hard to install because of the stiffness, the OTC / Honda OHV Clamp tool must be used, otherwise its just a fruitless joke. I installed them, and they also are stiff enough for the factory timing procedure to cause timing skips. This is fixed by following a friend's guide on getting an extra "click" out of the tensioner, then carefully reinstalling. These springs are BC, so I'm sure the revs will be crisp and I can set my redline higher. I will update once the motor is broken in.”
