124in. Engine Build (page 1)
Head torque specs and sequence. Like most aluminum motors, you are stretching the head bolts...not really torqueing them. At the last step. (the 90 degrees)
Running in the head bolts to begin torqueing.
The electric compression releases. The release is shown on the left. The right release has the S&S two piece tool used for installation slipped over to show how the tool is used, with the wire hanging out. Antiseize on the threads, note the regular spark plug compression washers for sealing. Torque as a spark plug. They are basically solenoids, meaning an electric current triggers a mechanical plunger.
With the releases installed, and the wires routed towards the intake. Slip the flame resistant covering over the wires. Lube the rubber caps with brake fluid dot 5 and slip the caps over the release. These releases are different than manual...or maybe I should say the head is. When open, they route the gasses into the exhaust port, so you don't really hear the common SSHHHH sound...no doubt the EPA prefers it also.
The pushrod tubes...large oring on the right goes up in the head, metal ring left slips down into the lifter block, with the o-ring beside it on top of it. Then the tubes are held in place, and the pushrods slipped down thru the head, thru the tube, into the lifter. With time saver pushrods this can be done later, after the rocker boxes and arms are installed. There's really no reason to buy them now, if you ever need to put them in, cut these with bolt cutters and slip em in then. These are good chrome moly rods, no reason to replace them till needed. Pushrods have 4 diff lengths...from longest to shortest...front exhaust, rear exhaust, front intake, rear intake.
Picture 53 shows the tool I use to turn over the motor to lower the cam lobes for rocker box installation, again unnecessary with time savers.
Rocker arm support blocks and arms, mostly self explanatory. Again clean all parts, lube shafts with assembly lube, and check for burrs that might cause sealing problems. Round hole in the center gets an o-ring...with one directly below it in the rocker box's bottom.

TRUST NO-ONE
You put a lot of time and effort into compiling all of the pictures and describing the process.
Thanks for all you've done for the members here, Brad!
