compression leakdown results!

well guys Since i have had my dart i have only really done a regular compression test to see what kinda shape it was in. I just bought a tester and ran it on a few cylinders....
So 1st i tested with low oil & cold engine since I was impatiant :toothy10:
got 30% leakdown, Then i ran to the store and got oil fired it up, pissed off the neihbors and tested again.
Got about 2-5% on it. Kinda unbeliveable since its stock bore and from what I was told it has never been re-built but looked like it had a cheap line bore once. I tested with all the other spark plugs in as well... dont know how important that part is.
I was trying to see if my tax return was going towards a re-build or getting the interior and rest of the car done.
What do you guys think!?!?!?
