Where to get these valve stem seals?

[someoneanywhere]

Hello again all!
I'm back with another who makes ´em question!
This time valve stem seal.
Probably viton or very high temp silicone lip seal with stainless steel energizer spring.
.375¨ stem size
.530¨ valve guide dia.
I know for sure someone over here will know these seals.
Thank you.

What do you use the engine for? If street, just get the appropriate metal positive seals (viton) to fit 0.530" guides and 3/8" valve stems. If you want those exact seals, just search for steel positive valve seals and look at images until you see them, but the ones I am talking about will work just the same.

The only seal like yours I can find (for motorcycles) will not fit your guides in 3/8" stems. These seals should work fine for you:

Depending on the springs your using, check seal od vs. spring id
