The Cylinder head on my 32 seems to be fine but would be interested in a reproduction new on at a reasonable cost.

Has anyone priced a comparable new replacement head for any modern mass produced car? I would expect that price by about times ten. We would be comparing hundreds of thousands of units to what 100? $1000 in my estimation is beyond dreaming. Having said that having new heads available for when mine cracks beyond repair would be nice but who will stock it. Probably not me at what I believe the projected price would be. The only way to get the cost down would be volunteer work to scan and create your tooling or molds. This could be a worthwhile ebpndeavor of the VCCA if it is to be involved in the preservation of these old cars. Even with a lot of good will and free time I expect the price of a machined ready to install valve train head to be upwards of $2500 US (more for us Canadians). Now if only a head would be keeping me from finishing my car I would look at that as a fair price. I bet a head for my Caravan would be close to that.

There is currently a retired Master Patternmaker named Dick Alcock who makes new exhaust manifolds for Pop'en John type engines. I do not have his info, however;

does have. I have tried to locate Mr. Alcock without success. Perhaps he will cast you a new head?

Since ford's have more replacement parts available for 29-32 vehicles. I did a Google search for "1931 ford engine heads". MAC's Auto has a cast iron head for $346.00 this may provide some insight for a 29-31 Chevrolet head cost target price.

There are some big differences notably flat head vs valve in head and four cylinder vs six. I think four times that cost would be more likely.

If the simple head for a flat head four is $346 the six cylinder overhead valve head would be at least five times that amount.

Another casting option is the ceramic shell molding process-it is currently in use for engine heads. A wax pattern is created (software will calculate the shrinkage) to factor the final size. Silicone rubber molds are created to prepare the wax patterns. The wax patterns with sprues and gates and vents are added. The wax pattern is dipped in a slurry and coated with silicone sand (10 coats). The ceramic shell with wax pattern has the wax melted out providing the cavity for the metal to be poured into. All sprues gates and vents are cut off and maching would be required. Tremendous surface detail can be achieved with this method. I would think that a 3d scan of an original head would be required at the onset.
