Alright its time for this 3 heat cycle thing. Yes I know my brain day by day is going south.
But all my rebuilds 'too many' I'm talking about valve in block engines like a Cadillac
V8 346 v/s a 337 Lincoln. no mention of heat cycles just torque to specs all makes: Last
summer we built a massive 275 hp Hercules 6 flathead torque to specs. Thats it. So whats this, a small V8 Ford thing. And then my cobweb brain says if the factory had to
do 3 heat cycles for "i'll throw a number 5,000 vehicles a day" not possible and I have
no doubt the dealer did that, because in my youth worked at uncles bus co. Ford shipped the cowl chassis to the body builder like Superior Ward etc no dealer was involve'd. And I doubt the body co. fooled with torquing heads. Then we had two Ford
city buses 1946 I think looked as a 59AB air brakes and ran an run until the 70's no
body ever re torqued those heads ! so I say this is a myth. The torque wrench is only
a tool, and this tool only tightens nuts and bolts evenly that the key...

oh I gonna get hammed from this one ++++
