valvespring question

Hey,

I am getting the texas speed 228R cam for my 6.0L. The specs are 228/228
.588/.588 on a 112 lsa.

I was wondering if you guys thought it would be worth going with the dual PRC spring kit. Its about $110 more than the single spring kit.

I was also wondering if I need special valve stem seals. The thunder racing kits I was looking at came with them, and this kit doesn't.

Thanks for your help.

The seals they use are for the 97-98 Corvette, 98 Camaro. It is a seal only, doesn't have the washer to go between the spring and head. Be sure you get the shims you need to replace that part.
