NOTE

If no intake valve seat inserts (1) were taken out, go

to frame 23.

Two sizes of intake valve seat inserts (1) are used in

these cylinder heads (2). Cylinder head can use a

combination of intake valve seat insert sizes. Measure

each intake valve seat counterbore (3) to tell whether

to put in a standard size or oversize intake valve seat

insert.

Readings must be within limits given in table 4-48.

The letter T shows a tight fit. If readings are not

within given limits, throw away part and get a new one.

1.

Measure and note inside diameter of three intake valve seat counterbores (3).

If diameter is 2.0580 to 2.0595 inches, this is a standard size intake valve seat

counterbore.

If diameter is 2.0680 to 2.0695 inches, this is a 0.0100 oversize

intake valve seat counterbore.

NOTE

Used intake valve seat inserts (1) that were not worn

were tagged so they can be put back in the same place.

Because machine shop may have machined some standard

size intake valve seat counterbores (3) into oversize in-

take valve seat counterbores, some intake valve seat

inserts may now be too small.

2.

Measure and note outside diameter of each intake valve seat insert (1) to be

put in.

Standard size intake valve seat inserts go in standard size intake

valve seat counterbores (3).

For 0.0100-inch oversize intake valve seat

counterbores, use 0.0100–inch oversize intake valve seat inserts. Refer to

table 4-48 for sizes of intake valve seat inserts.

3. Measure fit of each intake valve seat insert (1) in its intake valve seat counter-

bore (3).
