Is there a beehive spring that will fit the stock LT1 heads without machining and other install issues?

I am considering 1.7 or 1.6 roller rockers and a spring change on the stock cam. I should change the cam, but with gas prices the way they are, not sure the power is worth the fuel cost.

I would expect to need shims, locks, and retainers, but I was hoping to get it done without pulling the heads.

Thanks

I just had the 26918 beehives installed with comp cams matching chromoly retainers, spring seats, and +.050 locks. This fits very well. The installed height ended up being about 1.74".

I couldn't get the beehives installed with the heads on the car with the spring compressor I had, so I just pulled the heads off and ended up redoing the heads anyway (more porting, 3 angle valve job, resurface) and putting in a different cam, 224/236 CC blower cam.

I just got the car running this week, so the jury is still out. Love that cam, it sounds great and idles very nice.

 

Yep I do these puppies all the time, just like EDS Z28 said.

Thanks for the information guys.

I followed your lead and checked out the springs on the comp cam website.

Since I am staying with the stock cam. I was wondering if I needed the spring pressure that the 26918 has.

The 26915 seems like the same spring with a lower seat pressure.

Any thoughts as to which would be better?

thanks

Beehive springs on stock LT1 heads[QUOTE]

advanced tech ?????

 

[QUOTE=aggiez28]Beehive springs on stock LT1 headsThey are the most advanced type of spring out there, GM is supposed to have spent 20 million in development.

If my post with a real question was a waste, how useful was yours?

Bringing this one back from the dead.
I have a stock LT1 in my road racecar. By rule, the engine must be 100% stock. One of the things we can change is valvesprings. I'm looking to use the beehive spring to get rid of some un-needed weight on the valvetrain. Since our class has HP/TQ # limits, I'm not looking for more peak power, just a broader curve. Right now the hot ticket spring cost wise is the LT4 springs.
Would an OEM LS1 spring work OK? Can I use the LS1 retainers and all? I see alot of folks sugesting the 915's from Comp for what my needs are. Is this still the case? I'll be getting a set of heads rebuilt in the next week or two, and was hoping to address any improvements I can make under the current limit of the class rules.

 

26918 springs, 787 retainers, stock seats, and stock locks.

 

I ran stock LS6 springs with LS1 retainers and my LT1 Locks on my 218/224 CC. Now that I went with a custom cam 22x/23x I upgraded springs to the 26918's for the seat pressure I needed for this cam.
