Hi Guys,
I'm installing PRC Dual Springs on my Dart 225's,the springs are currently on my stock LS1 heads with about 800 miles on them. Obviously I'm going to have to replace the valve stem seals,does anyone know the part # for pre 2000 exhaust stem seals for an LS1.
Thanks

John

 

Intake/Exhaust - 12533586/12457652

Those are the part numbers I have.

 

excellent ,and they are just stems without seats correct?

Thanks

 

Yes, the older style umbrella seal. I just my parts box and confirmed the numbers. Do you need the part number for the newer style?

 

I'm looking for the seal that goes on the stem only, I was told 2001 and earlier exhaust. The seals I have, have a spring around the top of the seal and press onto the stem no seat. The PRC springs come with a hardened seat so I can't use the Dart seals.
Does the newer style have a seat?

 

The newer style seals have a seat and look exactly like the Dart seals.

 

We can sell you the seals you need. They are the ones used with our spring kits and heads. They should be exactly what you need.

 

Thanks for all the Info Vettenuts, Gunner I will call you today.
Thanks
John

 

No problem, just call or PM and we will get you some seals on the way.
