I have ported/cnc'd lt1 heads that are milled down to 54cc chambers. This is on the stock pistons & bottom end. What head gasket would put me where I need to be? Or what would the compression be with stock size head gaskets? Help is appreciated as I want this engine in the car ASAP. Thanks in advance

You'd need a Felpro1094 .015" rubber coated shim gasket to hit that 11.5 CR.
They don't come with the LT1 reverse cooling holes, so use your old gaskets as templates to add the holes in the SBC gaskets.
Next best would be to use the .026" VR or Mr.Gasket (I don't know which is still available) with LT1 specific cooling holes to give about 11.2 CR.
