Whats the dowel pin size difference on 6.0L heads

I've been looking at picking up an extra set of heads for my 2005. In my search I have come across the fact that there are two different dowel pin sizes on the 6.0L heads, 18mm or 20mm. Can anyone tell me what the differences are in the heads, and if they are interchangeable or not?

Everything you ever wanted to know about cylinder head commonization.






Subject: 2006 6.0L Diesel Power Stroke Cylinder Head Commonization
Effective Date: Ford Production Assembly Plants - January 11, 2006
Kentucky Truck Plant (Super Duty) & Lorraine Assembly Plant (Econoline)
Description
Changes are being made to the 6.0L diesel cylinder head, head gasket, crankcase block, rocker
arm carrier and injector hold down clamps for the 2006 Super Duty and Econoline Program. The
action is taking place to facilitate/communize the International manufacturing process for the
upcoming 6.4L program. The 2006 6.0L used in Ford vehicles after January 11, 2006 are being
referred to as "Commonization Engines".
Part number details are provided on a separate excel spreadsheet.

Figure 1 - New cylinder head
1. Carrier boss bolt holes M10 x 1.5
2. Injector clamp bolt holes (relocated)
The new cylinder heads have several casting changes including a slight injector clamp bolt hole
relocation (2, figure 1) and the carrier boss bolt hole size and location changes (1, figure 1). New
cylinder heads also use 32 mm cup plugs replacing the old 28 mm cup plugs.
The cylinder head gasket is also new to accommodate the new 20mm cylinder head location
dowels. Pre commonization head use 18mm dowels
Note: At this time the new cylinder head assembly is not interchangeable with the previously level
head.

Figure 2 – Previous Level Cylinder Head
1. Carrier boss bolt holes M8 x 1.5
2. Injector clamp bolt holes (original locations)
Note: The previous level cylinder head assembly is not interchangeable with the new head.

Figure 3 - New Block Assembly
The new crankcase (block) uses two 20mm cylinder head locating dowels per head.
The old crankcase (block) uses two 18mm cylinder head locating dowels per head.
Note: The new and old block assembly is not interchangeable. This affects replacement of all 6009
short blocks and the 6010 bare blocks.

Rocker Arm Carrier:
Figure 4 - New Rocker Arm Carrier
Casting changes to the rocker carrier provide increased clearance for new injector hold down
clamps (figure 6). The new carrier also uses only 2 bolts and locating dowels to attach the carrier
to the head.
The new rocker carrier is serviced in a Rocker Arm Carrier Kit which includes the rocker carrier
cover, gasket and necessary dowels.
Note: The new and old rocker arm carrier kits are not interchangeable.

Figure 5 – Previous Level Rocker Arm Carrier Kit
The old rocker arm carrier uses 4 attaching bolts to hold the carrier to the old cylinder head (figure
2).
The previous rocker arm carrier is also serviced in a kit which includes the rocker carrier cover,
gasket and necessary dowels.
Note: The previous level rocker arm kit is not interchangeable with the new kit and will remain
available for service.
Injector Hold Down Clamp:
Figure 6 - New Injector Hold Down Clamp Assembly
The tail end of the new injector hold down clamp is being reduced to avoid interference with the
rocker arm carrier wall. Injector hold down clamp bolt torque will increase from 24 lbf·ft to 25.8 lbf·ft
and bolt head size will increase from T40 to T45.
Note: The new and old injector hold down clamps are not in interchangeable.

Figure 7 – Previous Level Injector Hold Down Clamp Assembly
Note: The new and old injector hold down clamps are not in interchangeable. The old injector hold
down clamp will remain available for service.
