I just wanted to post some pictures of a Morton and Brett Head Rich is running on his 1926 Dodge Banger.
Many of you have seen Rich's build thread (http://www.landracing.com/forum/index.php/topic,6487.0.html
) but I thought people would find it interesting to see some close up pictures of a very rare speed part from the 20's for a non-Ford make.
This head is on loan to Rich Fox by a collector in Hayward, CA and will be run at Bonneville in Rich's '29 ford roadster.
It has three exhaust ports, the center is for two #2 & #3 cylinders
It has two intake ports shared by the #1 & #2, #3 & #4 cylinders respectively
Note the holes under the ports along the bottom edge of the head? Those are the spark plug holes, they enter the combustion chamber at a 90 degree angle. The combustion chambers are so tall that the plugs come right out on the side.
Here a closeup of one of the intake ports. The head bolt runs through the center. Rich plugged the top of the hole and the stud ends inside the port so the nut and washer end up inside the port. Rich figured it was better than the entire stud running through the port.
On the exhaust side there is a small "alcove" for the head bolt under the end ports.
Here is the top of the head, Rich fabbed his own rocker shaft supports as the originals were missing. There are old repairs evident, apparently these heads had a habit of pulling out the rocker shaft supports. It seems the priginal setup had 4 pedestals to support the shaft. All the holes were plugged when Rich received the head.
Here is the rocker arm assembly Rich fabbed, the rocker shaft and roller rockers were made by a professional shop, but Rich fabbed the plate and the pedestals. Sorry we don't have any shots of the original rocker arm setup.
Here is the underside with the massive combustion chambers showing. The spark plugs are in so you can see how they mount to the head.
Here is a detail shot of one of the end chambers. The "bump" was added by Rich because the head as cast/machined originally left only .040 to seal between the head bolt and the combustion chamber. When preparing for final installation of the head to the engine we discovered that on the #4 cylinder the piston, which has a massive dome, was hitting the "bump" Rich had welded in so we needed to grind it down with the die grinder to give more clearance.
The head has one water passage for outlet at the front of the head, Rich made a plate with an AN fitting to attach to the water pump system in his roaster.
Here is a picture of the head on the engine. Note the water lines are connected. Inlet goes to the block and outlet through the head.
I will get some pics of the valve cover.
Thanks for look'n, hope you found it interesting.
