Ok, My motor is stock the car just ahas bolt ons and N20 and my valve springs are stock and 12 years old so I want to swap them out for something fresh and something better , whta springs should I use on a stock motor?

the car is a 1994 and the mods are in the sig.

Thanks.

 

LT4 valve springs locks & retainers will work well, and they are cheap! (~$40)

Stock engine? I'd say you're a good candidate for Beehives. While you're at it, throw on a set of 1.6RR; either the Crane Golds or the Pro Magnums are fine. Both are in wide use and you can find lots of threads talking about both.

 

Are the GM Performance lt4 roller rockers the same exact ones as the
Crane Gold?

 

Unfortunetly I dont have the budget for RR's right now, do you have a part # for the beehives? and will they work with the stock RR's?

 

TTT does anyone have an idea?

 

To tell you the truth if I were you I would just save up for a litttle while longer till you can affrod the rr's so you won't have to take the rockers of twice, saves a little work. The comp 918 springs are the beehives, as far as them working with stock rockers I have no idea.

 

Just go with the LT4 stuff mentioned above.

 

ok thanks, and the last questrion would be ... where is the best place to get them? or if anyone has a part # that would be great!

thanks.

 

Go with 918's cause if you ever do put RR's on, the LT4's are gonna be pushed to close to bind. They pretty much are close to their limit. And if you ever cammed it, they would be junk.

 

The LT4 springs are cheap even if you buy them from a dealer w/o a discount.
By the time you pay for shipping from gmpartsdirect you may find it's a wash.
