rocker Shaft install question

[Dirty325ix]

when inslating the rocker shaft do the big holes point downwards twords the head

and are the shafts specific to their respective sides

[jlevie]

The shafts aren't side specific. The correct orientation is when the locking tab notches are in the correct position at the front of the head.

The tabs all line up but the can line up with the large holes pointing up or it can work with them pointing down

which is correct

i assume the point down twords the head

There should only be one way they can be installed. With the slots that the rocker shaft retaining plate fits into facing in towards each other.
Check this out.

yea you where right in the first place i just had to look at it and think

[Dirty325ix]

it looks like the rocker shafts are in at slightly different angles now that i have all the clips on
but the retaining clip that goes in at the front of the engine fit, just had to force it a little.

is that 1 degree of difference going to be a problem

hope fully not
look at the picture attached, i think im just being critical because its ma first rebuild

If the locking clip is fully seated, the shafts are now in their correct position.
