Comp 918 VS REV dual Springs Which springs are more durable ? ( I know rev duals have an extra protection, since they have a second spring, just in case the first one breaks, but that doesn't make them more durable...
So which one is more durable ?

Re: Comp 918 VS REV dual Springs I purchased a set of 918's and later swapped for a REV set, more insurance. My machine shop tested the 918's and tested at 340lbs., the REV's went up to 375lbs.

But now on my 422 iron block , beacause
of the high lift of the cam (236/240 601/609lift)
I´ll install the REV 1116.
The REV´s are for up to 625 lift.

Re: Comp 918 VS REV dual Springs I prefer 26918s. A know a local machine shop around here recommends the REVs over 918s, but he also has a speical <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" /> interest in REV and therefore pushes REV products. I find 918s to be queiter. If I was going to go to a double, I'd probably do Comp doubles.

Re: Comp 918 VS REV dual Springs I had 918s on my Cartek Stage 2 heads, I swapped them for Rev 1116 Duals for more peace of mind.
I have heard of 918 springs breaking resulting in damaged engines.

Re: Comp 918 VS REV dual Springs How much lift are 918s rated to. I was thinking of switching to bigger springs for peace of mind also, but do you think i will have to worry about it with a 59x lift?
