Re: Advice on removing engine? -New Pics

My block is at a machine shop awaiting its turn at being looked at etc., but I held on to my heads so I could get a little more personal with them.

I thought the forum would like to see a few pictures after my head disassembly.

The valves have the Packard (and Eaton) logo on them. No telling how old they are but they seem in decent shape for their age. The valve seats need to be cleaned up but each valve is proud of the seat so no extreme seat recession.

See the picture of the valve seals. These big, hard, plastic ones were on the exhaust valves. I'm assuming these are the 'positive valve seals' The intakes had some evidence of a seal there too. But not much left of them.

There is evidence of valve guide wear. I don't have a split ball gauge so used a dial gauge on what felt to be the exhaust valve with the most wobble. It's peak to peak difference was ~0.015" so I probably need to have the guides redone with whatever I do with valves.

My heads are very old, notice the casting date of one of them as January 1955. The valve spring retainers/seats don't seem to be hardened (easy to score with a file). Are the ones sold by Merritt for $5 each, hardened?? They don't say online.

Besides price, are there any differences between the valves, springs, retainers etc sold by Kanter, Merritt, Egge, etc?

My current plan is to find a local machine shop and have them:
1. really clean out all the passages
2. Redo the valve guides.
3. Probably replace the 16 springs
4. Probably replace the 16 valves?? (they seem like they can be cleaned up and still have margin on them, but they are not the SS type. etc etc.
5. Replace the 16 valve retainers with hardened ones
6. Forgo hardened valve seats, just have them cleaned up but not sure on this.
7. Clean inside of rocker assembly, grind rocker tips etc


Any advice?

thanks,
Bob
