Its a little harder than installing single springs since your doing valve seals at the same time, but once they are in you have much more piece of mind.

btw its cool you didnt break anything. It could of been ugly. I saw some pics of Vince's motor when a high mileaged 918 went.
when I install a cam and spring package for someone I require that they run the patriot springs. Spring failure is a serious *** issue, don't try to cut corners in that area.
