Do you know how much has been removed? Are you running high boost? What's your setup?

I have no idea what they removed from the head or block.My set up is arp bottom end with stock t2 crank and rods with ross pistons 8-1/2-1 comp. Polised head with back cut valves fm475 cam springs and follower. 2 peice ported intake 52mm throttle body 52lb injec fwd stg5 computer 3inchis exhaust. I was runnin 20 psi boost on stock garret. I bought new turbo and a tbi header for the car. Plan is to stay around 18 to 20psi on street. Turbo is precision 5431.

I would add the .020 copper shim or run the thicker Cometic then. If you want to get accurate, you can CC the chambers, pistons and work out exactly what thickness you need.
