Sometimes in a high-powered engine, when the bolts are replaced with high strength studs and the torque spec is increased, the bearing bore will distort and the block will require align-boring. Align-boring should be avoided if possible because it can potentially cause problems with the oil pump gears and cam timing.
In a high-powered forced induction engine, studs might be needed- but not for a mild NA build. The stock torque-to-yield bolts are designed to start to stretch before the point of where things might start to distort.
All of the many bolts that hold the bottom end together are cleaned, lubed, and in place.
Howard lightly tightens the main cap bolts by hand, getting them ready to be torqued down.
Howard torques the bolts in a cross pattern in three steps up to the maximum torque, then uses angular tightening to bring the bolts up to their final tightness. This is standard procedure with OEM torque-to-yield bolts.

“The Coyote is interesting because it has a 90 degree V-angle, which is greater than your typical modern V-8. Ford chose to keep the 90 degree V for better NVH reasons, when most other manufacturers like Chevy run a tighter V-angle to build a more compact engine.”
That is completely untrue. Do you know what a V-8 engine is?
No, it’s not, it is completely true! If you are going to troll, you need to be smarter.
