valve train intall help questions

ok Getting the heads tomorrow for my 1969 273 la dodge motor.

got the torque sequence and torquing lbs for the heads and manifold.

if someone who absolutely knows could refresh my brain on how to re-install the stock rocker arm assembly and push rods.

I took everything off and everything including the push rods, bolts, rocker assembly has been labeled what side they came from and the order. I am all ears. even a how to link, been looking nothing I could find.

I think I know but it's been 25 years since I took one apart.

motor is at absolute TDC. timing marks at 6 and 12 timing slash on 0

Are they stamped non-adjustable or ductile adjustables?

i'm not home to check the rockers for the code, but I will describe the set up. looks like hydraulic lifters, solid push rods, a bar which holds all the rockers, the rockers a shaped kinda like diamonds with nothing on the rocker to adjust, the push rods just sit in them. the bar bolts to the head.

I would do it with the intake manifold off, some take a stick or wire to hold the pushrods inline away from rockershaft mounts.

#1 Notch in shaft down, left side toward front, right side toward rear.

#2 Take complete assembly with bolts, rocker tips hanging down and roll them over valve stems aligning the bolts and dropping them in the holes.

#3 Get a few threads started as you place pushrod tips in the rocker arms.

#4 Tighten all five bolts 1/4-1/2 turn at a time to bring the shaft down evenly checking pushrod tips in lifter and rocker arm, this is the critical time when you don't want to tighten with a pushrod on the edge of a lifter.

#5 tighten all bolts until seated then torque to 210 inch pounds.

This is when you will want to consider priming your oil system when both side are on.

thanks that's what I kinda remember. Thanks for the notch reminder!!!
also last question 210 lbs of torque? i have been reading the rocker bolts should be about 30 / 35 lbs

no yes?

also since i want to get this right...you said...#1 Notch in shaft down, left side toward front, right side toward rear.
left when standing in front of car? left meaning passenger side?

The shop manuals had a misprint for several years. These are grade 5 (3 point) 5/16 bolts, so 30 ft lbs is way too much 210 inch pounds is 17.5 ft pounds

A wire coat hanger works great after you straighten it out.DO NOT over tighten the bolts Work around tighten them a little at a time
