Like the title says. Is there any reason why I would choose a particular brand spring over another? I'm pretty much decided on Supertech dual valve springs and retainers. Any reason why I would want to go with a single valve spring like Brian Crower?

 

Supertech.. There is many reason you wouldnt want to use Brian crower even if it was duals.. They fatigue and float valves.. Go with the supertech or Kelford Beehive..

thanks! I was gonna go with the bc's because they were alot cheaper, I'm glad I changed my mind =)

 

what kind of rpms will I be good for ?

 

In theory 8,500

 

prob just stay at 8 lol

and hoepfully I see you in L.A. soon!

 

Probably a good idea. Only been here for 3 months. Great weather, just not right now.

I live in Simi Valley

 

is there anything needed to be done to the head to accept dual valve springs? or is it the same as any other spring, just remove old ones and drop new ones in?

 

yea its been raining there like everyday lol. I'm trying to get stationed there =D

 

I am wondering the same. Any mashining required?

Also any opinions on the Cosworth valve springs, but they come without retainers.

 

you may or may not need shims...

 

I am running supertech springs in mine, highly recommended! With my GSC s2's of course.

I rev mine to 9k, wouldn't hesitate to do 9.5k if I needed to.

 

are you running the doubles? did you have to do anything to the head to run them or do they just drop in

 

I have a fully built head, and yes the supertech duals.

thanks for all the advice!
