I hear there is more involved in the install of a daul valve spring kit vs. a single valve spring kit, is there a drop in dual springs+retainers setup?

I don't plan on ever revving my car past 8K, so I figure the single springs + retainers will be plenty for me.

 

what cams are you running, if your not reving past 8k you probably don't need springs and retainers

 

I'm running the GSC S1's, I'm really only doing this for peace of mind. Just want to make sure I've got everything covered you know?

 

just go with singles

 

Skip the valvesprings altogether. GSC's have relatively low lift and do not require valvetrain upgrade.

Cosworths have 11.00 / 11.00mm lift and do not even require valvetrain upgrade to 8000rpms.

Over 11.00mm life cams and over 7650rpms is the time to upgrade.

 

I'd still like to do the upgrade as it will only make the EVO that much stronger and it's worth the money if it brings peace of mind. I'll definitely give your suggestion some thought TTP.

 

if you do Supertech you will have to do valveseals as well, because of there spring locator.. if you go with Ferrea there locator will not in without removing the seal..same goes with Manley. It certainly can't hurt you to do it! except your knuckles!

 

^^ Are you referring to Dual springs + retainers? I thought if I did singles I wouldn't have to do new smaller valves and seats.

 

What about the BR dual springs and retainers, any other install parts needed on those?
