Fuel system- original mechanical pump and



So here are the numbers. Oddly the cylinders on the passenger side were similar and the cylinders on the driver size were similar but the 2 heads were drastically different.

Driver side head
  • # 1: 160 psi
  • # 3: 165 psi
  • # 5: 160 psi
  • # 7: 163 psi

Passenger side head
  • # 2: 192 psi
  • # 4: 188 psi
  • # 5: 190 psi
  • # 8: 185 psi

Searching online, I am reading that may indicate one side needs a new head gasket. I do recall taking the passenger side head off so may have used a different head gasket- would that be the reason for the large difference? Any ideas?
I don't know why the difference from side to side, but that is like the difference in 1 point of CR or about 10 cc's difference in total volume from side to side.
