i bought 13 valve springs off someone on this forum and ordered 3 from summit (918's). the ones i got from summit seem to be shorter. i think they are the older .600 lift batch and the ones i bought off the member here are the newer .625 lift batch. would i have any issues running the 3 for a little while until i can find the new ones.

i am very impatient and wanna get my cam in NOW! and dont wanna wait until i can find the new springs cause summit doesnt carry them.

 

Sounds like you like to play with FIRE!!!

Do it right the first time. WAIT!

 

Take it easy!!! Do it right, or do it again... but spend more the second time.. heres what happens when you mess around with 918s: https://ls1tech.com/forums/generatio...l#post13804872

 

Why would someone sell on 13 valve springs? Makes me suspicious they are the older ones that break. Personally, I think you have 3 valve springs and 13 paper weights.

 

x2 I'm with you on this...

 

also they have different installed heights Valve opening pressures this all could possibly damage the camshaft this would be one time when patience is a virtue also are the spring diameters the same and different springs rates can effect valvetrain performance

 

yeah gonna buy all new ones. tryin to save money never works for me.

 

smart man patriot sells a good set or isky also pretty reasonable i have a set in my car and they work amazing

 

Do you have a garbage can? I wouldn't run the 918's for nothing. Step up to some Pacs or a double spring.

 

yeah i was thinkin of the PACs but didnt know if they were good cause i never heard of them.
