So the factory gasket needed to be replaced aswell as the head being cut/
Cylinder head was cut .030"
To compensate for that I ordered a .075 gasket from Cometic,(stock gasket measured around .02x".... did a compression test today, 125 across the board, My questions is would .045" drop the compression that much?(this gasket was thicckkkkkkkk) Turboing it anyhow, but just wanted to make sure

You didn't remove a cylindrical area from the combustion chamber, now did you? Decking the block would have netted you the correct chamber volume with a thick gasket, but the chamber isn't cylinder shaped.

You're messing with the quench area. Running a thicker or double head gasket is usually a hack to gain lower compression.
