I'm putting in kiggly beehives so I figured I would change the seals as well.

Supertech: http://www.cimotorsports.net/motor-s...l-set-evo.html

says it fits all valve springs?

Ferrea: http://realstreetperformance.com/sto...-evo-2263.html

OEM: http://www.tougefactory.com/shop/pro...ve-stem-seals/

or other?

 

Any will work as long as the springs are not DUAL. If they are then you would need to run the supertech ones.

 

^^ why do you have to run the supertech seals on a dual valve spring?

 

ah I see they have 2 kinds now. so they are all pretty much the same?

 

Because with dual valve springs the inner spring can pull a stock sized valve seal off allowing oil into the combustion chamber.

 

Right, The stock seal is too large of a diameter to fit inside the dual spring.

 

supertech have premature failure... there is too much play in them

 

How accurate is this statement? Im looking into replacing my worn seals and i do not want to but ones in that will just go out again in 20k miles.

Im running the GSC Beehive springs with S2 cams...

Thanks for any info..

I've had my supertechs in for at least 30k. No problems so far.

 

Thanks for the info. Super tech it is then.

What cams and springs are your running? Stock retainers?

Thanks again!

Also are you running these smaller inner diameter ones? Im only on beehive springs so i dont have a dual setup.

 

Kelford 272's with the Supertech dual spring setup and the 6.6 seals they come with.
They are made of viton if I'm not mistaken, so hopefully they would last longer.

Yeah, you can use the seals no problem with the beehives.

Good luck
