Great job on the engine.
I have 5.3LS L83 Cylinder heads. M12 X 1.75 X 135 bolts. Do you know the torque specs of mine?

What was the final torque spec on bolt 9 and 10 in ftlb
Everything is in the description.
Do you have to use the angle part?
With the TTY bolts yes. You can buy ARP bolts that are just a torque spec only.
9 and 10 what is the final torque pound?

Is it the same specs for a chevy 03 5.3L ?
Yes
I’m doing my right now but my torque wrench doesn’t seem to have the angle torque
And have the same bolts
You have to purchase one specifically for angles not all torque wrenches have it.
I bought a Durofix 1/2" ANGLE digital torque adapter. $85 on Ebay. For use with existing 1/2" breaker bar. Just doing one 2003 LS engine. Positive reviews. Maybe upgrade if I get totally bitten by the LS bug. 1982 Volvo LS swap.
Thanks for the well done Video.
2021 gmc sierra 5.3?
2003
Is this the same for a 09?
No torque specs are a little different.
@3rdGenC10s where can I get the 2009 spec I'm having a hard time finding them

2014 5.3 lt 10 bolt ?
This is all o could find for a Gen 5 www.silveradosierra.com/threads/2016-sierra-5-3l-head-torque.731535/
9 and 10 end up 50lb foot torque?
No, they end at 50 degrees.
why not go to 65ft pounds and send it. thats what some guys do
I have the tool to do it to GM spec instead of just “sending it”
