for a moment i thought why so fine tollerances in automotive maschining - then i remembered you use banana dimensions and 1/1000 for you is only a rough dimension of 0.0254mm im working in QC - producing dosing and packaging equipment for medical and food industry as well as purpose built fine mechanics - with maschines like the newest DMG Mori and KERN-CNC positional tollerances of 0.02mm and finer for holes and diameter tollerances of + - 0.0025mm Roughness RZ of 0.15µm (micrometer) on parts with up to 6tonns - ever had to let a work piece acclimatise back to exactly 20° between milling work steps to be within tollerance and needing to leave it in the maschine to not have a reset error? tension relieve glowing after rough milling

But my love of motors, which started when I was 12 years old rebuilding lawnmower engines through the 60's and 70's hot rod phase, up to just general restoration/repair help for friends and those that needed my help. I really enjoy seeing the old stuff happening still.. I miss it a lot and now can get a bit of a fix through you guys.. Carry on and thanks again..

One of the things I've noticed over decades and hundreds of engines. Is that some engines are more sensitive for the need for retorquing, after the installation of a new head gasket. Some engines you can get away with not retorquing. Others if you don't it's just a matter of time before they fail.

In the good 'ol days of Nascar, they would obtain a well used truck engine that had been well seasoned from the countless heat/cool cycles. The warped block would then be machined to a concentric tolerance for flatness where gaskets met and the crankshaft bores checked for uniformity. Surprised that the crank bore trueness wasn't mentioned here. This warpage of the block and head is described as core shift and is very common. Almost everything fuel driven is this way to some extent.

out of curiosity. When machining the head, why do you surface before you work on the valve seats? I remember in your model A video you were talking about the valve seat machine using the the valve guide as a reference, or do you tram in the deck on the machine first? Because if you surfaced the valve seats first all to consistent depth, then you could deck the head to ideal valve recession clearances. Or is my thinking completely wrong? Thanks for the videos, really interesting stuff.
