I have a May 1928 engine, 5 bearing cam, block. I would like to find the correct head for this block. Is there a way to tell the differences in unmarked heads or did the earlier heads have the Ford script cast on them ? There is a 26 stamped on the lower head by the #1 plug and that's all the markings on these heads. Thanks, Pat

Neither is a 28 head. 1928 heads had no center water passage. Not sure of the exact month when the center water passage was added as I do not have a current Judging Standards yet. Still have the outdated version so I do not want to give wrong info as I am not sure if there was a change in the current JS.

I wonder if the center hole is mentioned in the SERVICE BULLETINS.
I seem to recall the hole being added about October 1929, but will check when I get time.Comment

Sometimes people ask about a B head, but they aren't specific whether they mean the Model A high compression head with the "B" cast in it, or are they talking about the Model B engine head with the large "C" cast in it. Besides the letter cast in each head, they are very easy to tell apart by the water pump.
The Model A head with the "B" cast in it has the regular...07-12-2017, 12:04 PM -
I am looking for a drawing of the stud locations vs the center line of the cylinder bores. I have a Winfield 7:1 crow's foot head that I need to have flycut to clear the pistons that stick up .062" above the block. I have been using a standard gasket, a solid copper gasket and then another standard gasket. That is not really working well at this time. It left me with a crack between the water...08-08-2018, 12:26 PM -
Here is the model sent off for 3D printing for the new B heads.

Tom W in particular will be interested in this.
The debate, at least in the Model A world, will rage on in perpetuity, despite that the Service Bulletins state to re-torque hot.
Anyway, I was wading thru my Motors manuals, going back into the early thirties, looking for some total advance comparison from earlier Stude 6-cyl with a 6.5 CR head, to the upgraded 8.3 head that was used...07-12-2018, 10:32 AM -
FYI, I installed a Snyder's 5.5:1 High Compression Head last month, and the distributor pin alignment hole was drilled too deep into the water jacket and leaked like a screen door on a submarine. Evidently, mine was not a one of a kind flaw. Just saw on eBay another one with the same problem. Evidently, there has been a production run of these with this problem. Maybe a new machinist there at...10-01-2018, 12:02 PM -
Ordered a 5.5:1 Snyder head via Mac's back in April. Just put it on Saturday night in preparation for the MARC national tour later this month. After I put it on, water was pouring out of the alignment pin hole under the distributor. Seems whoever machined this head drilled right down into the water jacket. Threaded the hole, installed an Allen screw with thread lock sealant and got the leak fixed....09-09-2018, 09:29 PM

Well, sort of. I've found some cracks in my old head between the water jacket and stud holes. I really would like to replace it with a sound (not cracked not warped) regular head. All the vendors sell only high compression heads and add that new grade 8 studs ought to be used. I was starting to replace the studs but at number 5 it snapped off and that's before I even got close to the back ones. So...09-06-2018, 03:38 PM -
Finally broke down and got a set of the Ford Service Bulletins.
First thing my eye found was this on pg 375:
"Keep cylinder head nuts tight
When engine is thoroughly warmed up all cylinder head nuts should be taken up slightly. This operation should be repeated several times especially during the first 50 miles the car is driven. Attention to this detail lessens the possibility...06-19-2017, 07:53 PM -
A few years ago, someone gave me a truck load of model A engines that had been poorly stored. I saved 2 of them, but the rest were so rusted that I could only save a few parts from them.
My brother is more persistant, and sent me these photos yesterday of his attempt to remove a stuck head. I think the new engines being cast by Tod will solve this sort of problem.You do not have permission to view this gallery.

New Prus 8:1 aluminum high compression head installed. Can maintain 35 mph on hills I used to have to downshift into Ruckstell with. A noticeable improvement in performance all around. The aluminum head weighs 12 lbs. The old 3.98:1 cast iron head weighed 28 lbs.
