Ok so here are some pics of the dropped valve on cylinder 2. A quick recap, I was installing a new dist., loud back fire, no crank as it was stuck, free motion limited, scoped and found dropped valve. The questions I have for the experts:
1. How bad is the damage to the piston? 2. I am replacing the heads with new heads from HAM built on AA heads, should I replace the jugs and pistons? If so, which ones, as I read don't get Keith Black, something like that... 3. If I am already here and don't know the true inner workings, should I tackle the whole engine as a rebuild, mind you money is tight with having to drop $1400 on new heads. If new cyl and pistons are needed thats another hit. I guess bearings and seals are not much more. Don't think I would need to mess with the crank and rods? Pics:      |
