most of my valve springs are broken

the 918 are supposed to be the ovate springs. Looking at your broken spring picture i agree that they are not.

Good ol' buyer beware eBay. Sucks that kinda thing happens on eBay too.

Yea i do alot of buying and selling on ebay and have had no real problems. I bought these springs from Alantic Speed on ebay. I talked to comp and they said that Alantic Speed was a good place to buy from so I don't know what the heck the deal is.

I kinda think the springs were not the 918 springs or if they were they must of been rejects. They didn't even look the same as all of the other 918 springs out there.

is there a reason when you upgraded the pushrods you went to 7.425" instead of upgrading to hardened 7.400" pushrods? think there might be a connection there, i don't know just bringing that to your attention. your stockers are 7.400"

yea the guy at comp said that's what i needed because of the smaller base circle but this time I used the stock.

All aftermarket cams have a smaller base circle than the stock cam, so to maintain the same lifter preload you can add 1/2 the difference in the base circle diameter (base circle radius) to the pushrod length to maintain the stock lifter preload. Not doing this can result in a noisy valve train.

Hey vettenuts, you know when I put it back togethor I used the stock pushrods and I was amazed that it doesn't tick any more than with the longer pushrods. Maybe they were too tight
