Just call Thunder or Scoggin-Dickey Parts Center (SDPC)
They normally have these in stock.
BTW 11.25 isn't happening unless you mill the heads more.
You will be very close to 11:1 with that combo listed above.

Do you already have the LS6 heads or the stock heads?
If you have the LS6 heads and they are already milled your in the 10.7 area.
If your still stock top end you right at 10:1 with LS1 heads.
WWith NON mILLED LS6 heads right at 10.5:1

No i have LS6 heads decked .010 is there a way to get to 11.25:1 and still be safe on the P/V clearence running a 231/237 TSP cam.

Would like to do the math the gaskets are expensive.

thanks chris

TSP has the Cometics in both .040" and .051". As for knowing what your p/v will be there are a lot of variables and every motor is different, but I would say that a .010" mill with a .040" gasket will put you on the hairy edge with that cam. You may be able to tweak a little more p/v by degreeing it.

Flycut is the only safe way.
To get 11.25 with having the heads milled on .10 you would need something like a .025 gasket which I have never seen used.
A .030 gasket would get you just over 11.1:1
