Aerovee #5 (Cylinder Heads and Valve Rockers)

Posted by on December 30, 2014

Total Build Time: 788 Hours.

For continuity purposes, this post will include my progress on the cylinder heads, rocker assemblies and valve pushrods. My next post will include the issues I’ve faced with the Aerovee cylinder heads.

The cylinder heads were pretty dirty with shavings, I spent over an hour per head cleaning and filing out all the burrs.

Cylinder head installation, per the manual, begins with inserting copper gaskets into the heads, then positioning the pushrod tubes.

I cut the valve rocker pushrods per the pushrod measuring tool. It took a bit of force to press the inserts into the pushrods after they were cut to length.

Below is the washer allotment I started with for the left side rocker. The final arrangement is noted in my manual.

When installing the rocker assembly, it becomes apparent that several head studs will need to be trimmed in order to clear the rocker assembly.

I set my rocker spacing per the manual, offset in order to rotate the valves on every cycle.
