Default Best head gaskets for a 408 LQ9 w/turbo

I have built a 408 LQ9 with trick flow heads. 10.5-1 compression. The head gasket blew after 1000 miles at about 12lbs of boost. After I get my bigger A/R turbo housing I will be increasing boost as much as 20lbs. What is the best head gaskets for this application to use. Thanks in advance.

Sorry I guess I am a little confused. I am a little new to this.

The LS9 head gasket from ZR1 Corvette. Google "GM LS9 head gasket" and the first few links have them for sale.

GM part number 12622033

LS9 is good or Cometic if you want a custome thickness. We can help you get something made
