Been looking over valve seals, and Thunder Racing offers two different types, one which I assume is the standard LS1 Valve Seal, and the K-Line brand...

has anybody ever used the K-Line? I know they're well known for their valve guides, but for another $10-$15, how much better are their valve seals?

Valve seals, I just use GM. I used an aftermarket once on my daughter's Nissan and they came off and rode up and down with the valves. Bought the factory ones and problem solved. There are two types of GM, the 01 and earlier and the 02+ single seal/seat.

going to bump this out of curiosity...

using aftermarket seals on a Nissan vs. GM is a bit different in my opinion...

I want a seal that will do well, be it crane or comp, or the K-Line...the Viton seals on the stock GM ones I had with the cam obviously had a problem, though it could have been a ton of reasons why, I'm just wanting something that will help me in the long run as far as longevity

Well sort of maybe, I guess my point was the aftermarket seal was a different rubber compound and that was the source of the problem I was having with them. As for GM seals, not sure what problems you have had with them but they have been rock solid on every installation I have done with them.

how much do the GM ones typically go for at the dealership?

Last set I bought was around $32 discounted through a vendor.
