quote:I used the Edelbrock heads and their installation instructions stated:
"ALL ENGINES - A re-torque is recommended after initial start-up and
cool-down (allow 2-3 hours for adequate cooling)."
I checked mine and only got 2 or 3 bolts to move ever so slightly.
FWIW, I re-torqued my Edelbrock heads (ARP bolts) after the first week of running the new engine and got NO movement. All bolts were still at perfect torque.
