keithb7 Posted October 8, 2017 Report Share Posted October 8, 2017 (edited) Regarding tools, this partial list of tools worked quite well and got me the results I wanted. The hand grinding of the valve seats is not for the weary. Edited October 8, 2017 by keithb7 Quote Link to comment Share on other sites More sharing options...
Bryan Posted November 2, 2017 Report Share Posted November 2, 2017 Quick question - did you or anyone else notice how far piston heads in these engines come up to the top of the bore? Are they flush? Quote Link to comment Share on other sites More sharing options...

Are they flush? If I recall, I believe they are flush with the deck, but I don't recall 100% Quote Link to comment Share on other sites More sharing options...

greg g Posted November 2, 2017 Report Share Posted November 2, 2017 Because the difference between the 251 and the 265 was in the stroke, I believe the 251 piston came to about 1/32 inch from the top of the bore, and the 265 was nearly flush with the deck.
