Im getting ready to order crane cams dual springs so I dont have to do anything to the heads direct drop in but I was wondering if I had to buy the crane spring seats? let me know thanks and if I do would I have to if I bought 918s?

 

Do by the spring seats for the Cranes. They are cheap enough and they locate the spring like they should be. They locate on the inside.

If you buy the 918's you will use the stock spring seats.
