Putting a Gmpp single plane intake on L92 style heads on a stock 03 LQ4 short block. do I want part #1222-2 .045 thick or 1222-3 .060 thick gaskets? Does O'rielly stock these in warehouses or do I need to order from summit?

I used the .045" on my L92, worked great. If your heads are milled a lot, the thicker ones might help with bolt alignment.
I just tried getting the LS7 felpro single plane gaskets, and they were out of stock.
SCE gaskets has all these intake sets in stock for a great price, and shipped right to your door from the manufacturer. That is what I went with for the LS7's
GM has part numbers for this stuff too.
