My cylinder heads were wasted. Total scrap metal. The exhaust valve seats were cracked. Since I'm doing this on a budget, paying a machine shop to change valve seats wasn't an option.
In a huge stroke of good luck, another member on here from up in Oklahoma reached out to me and offered to sell me a set of heavy duty TBI heads (with the Stellite valves like I need) for a good deal. I talked Valerie into a road trip adventure so we got in my Honda and headed north across the Red River to Oklahoma for my new (used) cylinder heads. The guides were fairly tight so I knew they would fill my need.
First step was to soak them in a 5 gallon bucket of diesel to loosen the crud. Then, degreaser and soda blast them clean. I also got out my high tech cylinder head machine tools.
My mill.
Valve guide cleaner.
Valve spring compressor.
After surfacing the heads with a long sanding block.
I re-lapped the valves to clean up the sealing surfaces.
Exhaust valve before...
After...
New valve stem seals. I had to special order the exhaust valve seals (not shown) since they use the unusual larger stems. My gasket kit just included the exhaust valve stem seals for light duty applications.
Bottom end all together....
