I am installing a g5x2 cam ( 112 LSA, 232/240 Duration, 595/608 Lift ) and wondering could I run a set of beehives that support 625 lift or should I go ahead will duals ? Input needed.

x2 on the duals. I prefer the PRC .660s.

I had a spring break once and it was a dual and it saved my motor. Duals for me forever.

Ok thanks guys, alot of people were saying that the beehives would be fine but more people were saying duals for the safety. So duals it is.

Don't mean to hi-jack the thread but...
I have duals on my car, they were on the heads when I bought them and I was thinking about swapping them out as I'm paranoid; the guy who sold me the heads told me they didnt have much mileage.. but he coulda lied...
BUT.. if the duals will save me if a spring breaks I won't go thru the hastle??
How do duals work?

if you set up beehives right they are just as safe as duals. they are also lighter and easier on the valvetrain.

because of that thread i am now going with PAC nitrided beehives, ls6 valves, and Ti retainers. lighter = better.

I have personally seen 2 pac beehives break... and they were set up by a very reputable heads/cam company along with their custom matched cam...

I have always ran duals on my motor and always will...

I just ordered a Cam from EPS and he told me that he would not recommend Beehives either and he has seen way too many issues with them...

they had a bad batch go out that were prone to breakage. that has since been fixed. no way to know whether or not the ones you saw were bad or not. and they also have 2 different types of beehives.

not to mention beehives + steel valves is not a good idea either. in that sticky i posted it said that light weight valves should be used with beehives, not solid steel.

I replaced my stock beehives with Crane Cams duals to match their gold roller rockers amd moly pushrods and could honestly say the difference was very noticeable. Car revs much higher without falling on its face and that's even with stock cam and heads. Plus, I feel much better knowing a valve won't be dropping into a cylinder anytime soon when on the spray.

Hotrod recently did a good article on valve springs i suggest reading it there is a lot of good info

^^^^that was pretty good reading. i would say if under .600 lift the beehive singles would be just fine. anything over that i dont know if i would risk it without duals. that article really had some good things to say about the beehive singles, which makes me feel better since im going with the pac 1218's for my tr230 cam.

x2 on this. I had an inner spring break with my Torquer 2 cam, and thankfully the outer spring held up. Saved me a lot of repair/rebuild dollars.

Depends on your cam lift etc, with my old 231/237 i had dual Patriot golds, with my new 222/222 and a much lower lift, they were holding the engine revs back by 500rpm.
When a set of 1518 PACs were fitted, engine freely rev ed from it's held back 6200rpm up to 6700rpm.

brian_rs/ss

i would suggest the 1518's, they're a little bit stronger and good up to .637.

this thread has a lot of good info on them.

i would also suggest a set of ls6 valves. if not then at least Ti lock/retainers.

I was told that dual springs can be a bit noisier than beehives (the dreaded sewing machine noise).

Drewhelm

The "sewing maching" noise is more likely due to incorrect pushrod length. The springs will not make any additional noise. Stiffer springs in general result in more valvetrain noise from the valve snapping shut and hitting the valve seat harder.

brian_rs/ss

that would be a result of the more agressive ramp rates on the cam lobes. not the spring pressures.

^This. My Torquer 2 on XER lobes was noisy as hell. Now my PatG cam on LSL was slightly noisy, and adding YT Ultralites made it near silent except for injector tick on my 36#ers.

I know that on some beehive springs you can use your stock hardware such as retainers, locks etc. Are there any duals that can use stock hardware ?
