The comp 918's are rated to .600 and I think I saw a max of like .620 on this site or somthing. Will these springs be my best bet or should I opt for .650 springs
Thanks

I would go with duals just for the fact that they are stronger, and youcan upgrade your cam if you want, and not have to swap the springs. On the other hand, 918's will lighten up your valvetrain, so I would base it on whether or not you feel you may want to go bigger or not.

While the 918's will probably work, personally, I'd prefer to install springs that wouldn't be operating at their pressure limits. There are plenty of good dual spring sets out there for less ($) than the 921's...

918's shimmed at least .050/.060 will work.
I'm using Platinums since they were on my heads.
I would advise to use a 7.425 p-rod with .054 gasket, to reduce valvetrain noise. (that is what I use and it is much better)

Thx & let me know if I'm coming from out in left field...
BTW - why does the longer PR & chamber height equal less noise?
918's will work, but I stress the importance of running a dual spring from a safety perspective. While I may not have broken a valvespring myself, I know all too many people who have broken springs, all of which have had their motors saved by running duals. For the relatively cheap price, you can sleep a little easier knowing a valve wont drop if you break a spring.
If you want to stay with Beehive springs, PSI also makes a set in their 1500 series that are rated for a little more lift than the 918's. Just more information to look at

.054 thickness is GM graphite stock thickness.
Chamber is 62cc
