I personally would run some Comp 987's. They are a dual spring so they will be better for valvetrain stability. They also will fit stock heads with out machining. I've seen it done.

Oh yea...forgot about those...i'll probably be getting those with the cam 847 i found

So these are good for stock heads and seats and everything? Why are they so cheap?

The 847 has lots of lift. If you run it with 1.6 RR's i believe the lift is close to .595 if i remember correctly. Thats cutting it to close for me. I would at least want a spring good to .625. I believe the closer you run a spring to the limit the shorter the life it has. The problem with the 987's is that they come with huge seats, bigger than whats needed for the springs. You just have to notch a small corner off each seat so that they will sit flush against the head. This won't effect anything. My buddy did this on his 987's on his car probably 20k ago and everything is still fine on it.

K-Motion K800's are cheaper, and can be found in a Jeg's or Summit catalog.

I may have some Comps for sale... They were good with my cam (.587/.600)

Never experienced any float, even up at the 6500-6800 rpm range..

Make me an offer... I can have pics for you soon if you like...

I can't find the EX-612 on the list of springs with that link?

I'm finishing up my valvetrain setup with an 847 cam and comp 987 springs, I'll tell you how it works out for me.

Awsome, can't wait.

The most effective springs for .600" lift that cost the least to run are the Comp Beehives. I will not run the 612's over about .570 lift because they don't have enough seat pressure otherwise.

Once you count all the new parts you need to run and the Ti retainers to get a dual spring to work correctly they add up to more money in the long run.

Not that I know anything about valvetrains..... just make these hyd roller things go to 7500rpm without float.
