continued when it was discovered that some of the valve guides were
cracked, so these will need to be replaced while rebuilding the heads. It
was also clear that this engine did not have hardened valve seats and
stainless-steel valves to accommodate unleaded fuel and new stainless-
steel valves. The stripped heads can now be cleaned in the same manner
as the block, and then examined for cracks and warpage. According to
Herman, it is common for heads to crack between valve openings, but
these heads are in excellent shape.
The engine is now ready for the next step: machining and determining
the sizes required for ordering new internal parts.
