What sizes are they?

1.500 and 1.775....looking for new valves (or at the very least "newer") for port job.

I used to normally use Ferrea valves in all my head packages, however through flowbench testing and R&D, I've discovered that SI valves flow and perform just as well, at a much lower cost.

Let me know if you need a head porter - I'd be more than glad to discuss options with you.

Thanks,
Khai

Thanks Khai,

I appreciate the tip and went ahead with the SI valves! Saved some cash and it sounds like a really good valve!

Newer performance valve company. I purchased mine through Si Performance Stainless Valves From RPM Machine

Not sure what the Si stands for.

Here is the main website that I believe you could order direct from (found that out after I ordered). SI VALVES- ANTIQUE/VINTAGE ONLINE CATALOG

Hope that helps,
