Anyone use stock springs? I would be way better off to use cc 986 springs right?

 

They will probably break in few days if that.

 

I would no, that cam will make luch meat out of your stock springs.

 

Thats what I thought! So what springs do you guys suggest that will fit directly on?

 

i think i heard the beehives will work,i am from the ol skool so i would just pull the heads and have them done properly,987 springs titanium ret,etc...

 

No need to pull the heads to swap valve springs.

Crane 10308 or K-Motion K800 valve springs are good springs for the CC306. The beehive (918) springs will also work well.

 

why quote me?cause i want to do it correctly!he has many miles on these heads,just toss some springs on there it will be fine!!!! i think i would be concerned with loose guides,or how about making sure the retainer to guide clearance is sufficient.i rather be safe than sorry...

 

Actually these heads only have 1500 miles on them since rebuild. They were just running stock springs and I dont want to risk that with the cc306

 

i didnt think you could just put new springs on?? dont they have to be shimmed to make them all the same?? i thought that part was basically limited to the profiessionals?? thanks.

I believe you can just put them on. Not positive though

 

to be able to check the spring height,possibly shim would be a good thing go to a good machine shop or better yet e-mail lloyd elliot and ask him,he does this every day.....

 

Anyone know if you can install comp cam 986 springs without any special requirements?

 

i'm running EX-612's w/ my cc306 for many miles now and many 6500 rpms pull...they are rated to .600 and the cc306 w/ 1.6 rr does .544 and .576

i just installed them with the heads on the car and everything, didn't check the height, or use shims or anything. no problems yet!

 

Awesome! Thanks TransAmGT!! Sounds like a good deal to me. Anyone know where to get the ex 612s the cheapest at?

 

I believe you can get them from Combination Motorsports.
