Got into the valve seals this evening.
Wait...
All of the valve seals on the DS of the engine are gone. They are intact on the PS, however.
I have 2 sets of valve seals here, and neither fit the 0.550" guide diameter of these heads. Awesome. Now I'm looking for some that aren't the "umbrella" type to fit.

Been taking some time in the evenings to get the engine torn down and things that need it tossed into the ultrasonic tank.
Lots of crust down low, not much up top.
This engine never gave me an oil light, or so much as a low-oil rattle.
Pulled the oil pump cover off and it didn't look too bad, honestly. Going to toss a new Melling pump and pick-up on it though, while I'm in there. The harmonic balancer needs to be replaced and going to toss a new timing set on it, since I have it all apart.
Pulled the ECU harness out to do the modifications for the MS swap.
I took out all of the EGR and other mostly-non-working emissions stuff. Pulled the wires out of the ECU connector and fixed up a couple of things.
The harness is now ready to go back into the car.
I'll do the final wrapping, etc. once I get things in their final spots. I need to splice in the TPS harness to replace the non-OEM connector I used to get the car running, and make the connections to the injector harness. This is just going to be batch-fired, as I can use the 2 injector triggers I have and they ran the trucks this way, so it'll work. I didn't want to run 6 new injector triggers, for pretty much no gain. The fan control is getting slightly altered. The LO-speed is still controlled by the stock AC relay, but the HI-speed will now be triggered by the MS unit, and not the temp switch I installed originally. I'm going to retain the WOT cut-out for the compressor, and can trigger that in the MS unit as well.
Speaking of the MegaSquirt ECU. I guess I haven't talked about it in this thread (I think I did in my old, lost FEP thread)
What I'm using is a OLD MS1 V2.2 board unit. The same thing I have had in the TBird, for 20-ish years.
What I'm using to connect it to the factory harness is the almost as ancient adapter board by Scott Hall that I've had sitting on a bookshelf forever (and I almost sold it too). I was able to find the BOM for the components and de-soldered a connector from a junk EEC-IV ECU and put it all together.
Then with a short harness, you can connect it to the MS unit and all of the needed connections are made.
Kept me from going down the rabbit-hole to a more custom install with the harness, etc. I've done it. Didn't need to do it here.
Once I get things cleaned up a bit more, parts will start going back on the engine.
I also got a bunch of stuff to get the new Y-pipe made. I may, or may not, have purchased a bunch of stuff to be able to attempt TIG welding stainless with my welder...

That is a super beautiful car...outstanding. Good luck with the sale.
The HO cam requires 19 lb/hr injectors, the HO firing order (1-3-7-2-6-5-4-8), and a computer swap to at least a 1987-88 Mustang HO automatic ECU in order for it to run correctly. Just FYI.
