Casting call

The first set of heads off of eBay came in and were so-s0. One of the rocker bosses was either already damaged or got dinged up in shipping. A cleanup at the shop and the we find out the ports and some valve seats were pretty pitted. What does Alan think of a mediocre casting? Well, he doesn't like it too much. The hunt for another set of heads begins!

I began searching on Craigslist and just happen to come across a guy selling some of his surplus Y-Block parts locally. We went over at night and picked up a three speed and chose between two sets of ECZ-G heads he had. One set was loaded with valves and springs and the other was bare. I opted for the full heads thinking that they would probably be less likely to be abused if they were still together. The other heads were pretty rusted on the surface so I didn't want anything to do with them.

After a little bargaining, we were on our way back to the shop with more parts. A quick inspection the next day in the light revealed a couple of stuck valves, some pitted bowls, and one rocker mount boss that had been warbled out and a heli-coil inserted. DRAT!

We dropped them off back at the shop to be tanked and inspected. The results weren't much better then the first set. There was a broken valve stem still in the head and there was some pitting. Another set of questionable castings. Either of the sets could be salvaged with a lot of work but we don't want to mess with molested castings. The search would continue.
