Just went through this scenario on my 2001 with 126,000 miles. My low compression was caused by the exhaust valve and seat not sealing. Found this problem on 4 of 6 ex.valves. This is a BIG problem on these engines, and Ford should be ashamed for letting this problem go as long as they did. Found a very fair shop through ebay that sells rebuilt heads with special exhaust valve seats. PM me for more info.
