The '90 FSM says to tighten bolts using the tightening sequence to:

22 ft. lbs.

then 45 ft. lbs.

then recheck at 45 ft. lbs.

then to 110 ft. lbs. except #11 to 100 ft. lbs. (bolt #11 should be coated with Locktite 592)

The tightening sequence is as you're looking from the front:

#1 -middle bolt on left

#2 –middle bolt on right

#3 -bolt in font of #2

#4 -bolt in front of #1

#5 -bolt behind #1

#6 -bolt behind #2

#7 -bolt in front of #3

#8 -bolt in front of #4

#9 -bolt behind #5

#10 -bolt behind #6

#11 - bolt in front of #7

#12 - bolt in front of #8

#13 -bolt behind #9

#14 -bolt behind #10

You’re basically making a spiral from the center.

It specifically says do not apply sealing compound and to reuse head bolts only once. I'd get new ones, I've broken them upon reinstall and had to pull the head back off to get the suckers out. Don't know about the retainers.

ya the retainer have about 15 of us bafeld

 

but thay don't alow the rocker to line up corectly

[Oizarod115]

the rocker arms don't really matter but the spec on them is about 20ft/lbs IIRC,

 

i didn't have any problem getting the rockers and rods to line up but i also layed them out in order how they came out origionally, did you take note of which one was which? it shouldn't really matter but it may

[camo89]

there in order but on my motor i have gide plates

 

[camo89]

so i found out that the bridges can bend when removing them

 

 

orderd new bridges heading out to pick them up

 

 

my next question is on the valves
