Hey I have just ran a compression test of my car and all the Cylinders have Pressure of about 90 PSI. IS that just really low or is that normal for a 25 year old car. I have the late 73 block but have an early 72 head on it. Is my car at the time I should start thinking about rebuilding the engine because it is starting to use a lot of oil right now. Should having the low pressure be a concern?? SHOULD I REBUILD my engine? Will raising that Pressure Raise my HP???

PLEASE answer all my questions if you can...
