i was told that its not how high the numbers are but how close they are together ex. 130 128 132 130 is good 130 100 102 128 is not and is probaly a bad head gasket. if just one is lower its probaly the rings.
Should be above 160 is my guess. My d16z6 that I rip on everyday is all 160, and that thing is teh sux0rs.
