I'd upgrade to at least 918's IMO. Stock springs are good for stock cams and thats about it.
I have a set of 918's that I ran for 3000miles before I got TSP heads which had springs on them. $75 shipped and you can have them

Stock springs will not handle that much lift on that lobe. IMO, Comp 918 springs or PAC 1218 springs are a minimum for that cam. We always recommend springs and pushrods with any cam. We see stock cars come in all the time that are floating valves with the stock springs on the stock cam on the dyno. Wait and put springs on with the cam. Your wallet will thank you!

I was thinking about getting that cam too when I get my tax return, just really like the sound of it after watching alot of videos and seems like it makes lots of power even with stock 241 heads. My question is if you buy top of the line double springs that are good for up to .650 lift do you still have to change those out every 20k miles or so? I've heard guys on here say change springs every 10k, 15k, 20k miles!? Does it have alot to do with how hard you drive? How much lift the cam has? If I had to change my springs every 10k miles that would kind of discourage me from doing a cam swap, that just seems like an awful lot of money for me to spend in such short interval.

I would go with a double spring. I just don't trust 918's as much as I've seen go wrong with them. My T2 cam really liked the comp 921s, they are a beefy spring.
Dumb *** mechanic that put my motor together tried running the cam with LS6 yellow springs...can you say valve float?

20k I think I could live with. So its not how much lift that wears out springs just how fast the ramp rate is? I think I'd be willing to sacrifice some power to have longer lasting springs, sorry to hijack thread

There are alot of variables to valvespring life and one of the most overlooked is installed height. Proper IH will help control harmonics and lead to longer life. I could not find the vid I wanted but this one still shows the harmonics at play with an improper spring setup...http://www.youtube.com/watch?v=_REQ1...eature=related

I ran the Texas Speed Torquer cam for 2 1/2 years and 48,000 miles using the PRC dual springs...never changed springs...when I swaped to a different cam and heads after 48,000 miles I checked the springs and they were still within specs...people who change springs out at 10K, 15K, & 20K miles are throwing their money away. If you have a concern about the life of a spring pull the valve covers and check the spring pressure of the spring if it checks out good keep running it.
