Your engine is at maximum bore, sleeving is the next step with your cylinders,an expensive process.Your .011-.012 is larger than ford spec at .002 or the modern 'acceptable' spec of .005..Id do a valve job but wouldn't touch the cylinders,at the most I would do is a light glaze break and re ring,but I don't think its necessary from the readings.The high compression head will accelerate the wear already evident in the bore,that piston clearance will grow over time,faster than a stock head..that being said,how long it will last is arbitrary,but my advice is to run it and see,many pull the trigger and rebuild an engine with many useful miles left on it.
