Default LS3 Oversized Valves

I am trying to find one intake valve preferrably 2.2" that will fit in my LS3 heads. I believe the stem size is 8mm. Anyone know where I can buy just one custom sized valve? It doesn't have to be exactly 2.2...2.19 2.21 etc will work. I don't need expensive titanium or lightweight valves either, cheaper the better.

Thanks

Matt

The valve is not the restriction to making more power.

That is HIGHLY debatable.

Try Ferrea, PN F6280. They're about $26 each.

Thank you for the help! I am not running the valve, I am going to use it to flycut my pistons. The stock valve is 2.165 so I was looking for a little larger valve to make sure I get the cut wide enough.
