[AJD] JD A Block and Head combinations

[John Boehm]

A quick look at the Parts Catalog, told me in less
than a minute that all the A's from serial #488000
through the end of production used the same head
gasket, so it is not surprising that heads and blocks
sometimes get switched to tractors in different serial
number ranges from the original configurations. If you
are attempting to restore two styled A's without
arming yourself with as much literature as possible
(Parts Catalogs, Operator's Manuals, etc.), you will
make your job much harder than it needs to be.

I have several A heads and blocks for sale as shown at
