Took me a few weeks working on the heads after work to finish up the porting. No idea what they flow or if I made any improvements but I like to think I helped out.
Exhaust finished up on the first head. Finished out in 40 grit if i remember correctly.
Intake port finished up with ~120 grit
This is after they were finished being ported and had the valve job done on the Sunnen VS-20 machine. I also had the heads milled ~.010 before beginning the next step on the heads.
If you look closely you can see the beginning stages of timesert inserts being done on the far left spark plug hole.
Tap fully ran through. And all of them tapped for the inserts.
Shot looking down the spark plug hole at the fully installed insert. I could have sworn I took one from the combustion chamber side but can't find it in any of my albums. Final result is a fully threaded spark plug hole that should have no issues with blowing out in the future if I decide to add boost.
Next before assembling the heads I went through and bled down two full sets of lash adjusters. Came out with 24 that bled down fine and sorted through the rest to make a full set of 32. Extremely fun process.
Final install consisted of Factory valves cleaned up and tipped to proper height, new valve seals, new oem ford spring cups and retainers, BTR valve springs, new oil restrictors, bled down factory lash adjusters that were soaked and cycled in tranny fluid for a few days and copious amounts of Lucas assembly lube.
Putting these in order is proving to be a huge hassle. Between switching from photobucket to flickr then to google photos most of the original date stamps have been lost or modified. I'm doing my best to find as many of the pictures as I can.
