Received head assemblies from AeroConversions. Evaluated the clean up work to the castings. Cut, filed, and smoothed cooling fins around dual plug cuts. Fit-up of heads to cylinders indicates the studs will be much longer than necessary.
Measured stud length to leave 2-3 threads. Removed 0.275 in (7.0mm) from each cylinder stud. Procedure to cut studs to have 2-3 threads showing is to chuck stud into padded vise, measure with micrometer, cut, chuck into lathe, dress end with file, Applied Curil K2 to case end and snug into case saver. Pushed #4 cylinder bottom case saver into case, pulled it back and snugged into case.
