wtb stock 2" ls1 intake valves

[Kory 88Iroc lt1]

I'm looking for a cheap set of stock ls1 intake valves. I'm planning on taking the 706 heads from my 5.3 in for a valve job. I figured it would be a good time to add a larger intake valve, if I could do it cheaply.
Let me know what you have.
Thanks,
Kory
