[Fot] Spitfire Block

[dale oesterle]

Does anyone know the specifications of the recessed groove around the pistons in the later 1296 or 1500 block?  I want to convert an early 1296 block to use the recessed head gasket for the later blocks. Thanks Dale Oesterle.

for motorcycles was to drill the guide with a slightly larger drill 
until it was flush with the head, then heat the head to about 300 
degrees in an oven and drift out the guides with a stepped drift. Of 
course these are small heads and they are aluminum.
