Hone and run it, or machine shop?

I just measured 2 oversized stock-type pistons for Fords (2.3L and 2.8L) and they are .002" under the bore size for which they are fitted.

So you have a bit of wear in a couple of those bores. Of course, the piston fit diameter will not be all the way up at the top of the ring wear area.

Taper tends to wear rings out more rapidly.... 1000 miles is probably not showing this yet. If you are planning on keeping/running this a while, then I'd bore it. (But I never do hone jobs anymore... regardless. I am pretty strongly biased to starting fresh each time.... good bores is one of the key foundational items for a good engine.) I've re-ringed a couple of engine with more taper than you have..... and the results were pretty poor.

BTW, do you have a 4.000" standard to check your measuring equipment to?
