I have looked several times and haven't found an answer or only answers like "these springs should work". Can someone please tell me what springs will work with my 1.6 crane cam roller rockers with a 306 cam? I think the lift is .544 and .576 with the 1.6rr, which is higher than the 1.5rr that normally goes on the 306 cam. The compcams site shows a certain spring to use but it is for the 1.5rr. Any help would be appreciated, thanks.

 

Cc-26918-16

 

Ditto the 26918s. Here is more info >>

Parts needed to install Comp 26918 beehive springs on a stock
aluminum head LT1 (for iron heads just omit the spring seat).

7 degree hardware with 4705-16 spring seats (1.73" installed
height):

787-16 retainers
648-16 locks

10 degree hardware with 4705-16 spring seats:

795-16 steel retainers, or
794-16 titanium retainers
611-16 locks (standard), 1.70" installed height, or
614-16 locks (+.050), 1.75" installed height

For either installation you will need spring seats:

4705-16 spring seats, .062" thick

 

I looked for the 4705-16 seats on comp's site and on byunspeed......they say it don't exsist.

 

crane 10308 in mine...direct swap, no machining or anything

 

918's should work. Contact Bret Bauer, he can help you with 918 bee hive setups. Thats where i got mine.

 

Yep, me too...The 987's would work also.

 

So........can you use stock seats or do you HAVE to get the 4705-16 seats?
