no you dont and they dont excist for cheap. you have no need for them

 

ok thank you anyone know how much horsepower i will gain form these?

 

I don't think you'll see much of a hp gain from these, you just increase RPMs.

 

I dont have gov springs installed yet or even bought any but have looked into it. Has anyone had any problems with cam wear/wipeout from the difference in spring pressure? I havent heard of anyone having this problem but it seems plausible.
