We got a 1973 GA series 2-liter motor that had low miles but sat for a long time. The pistons and cylinders are gone, crank probably just needs ground, case is good, the 039-101-371A cylinder heads look great EXCEPT for one of the chambers. It is badly pitted from corrorsion.
Can it be used as is? Is there anyway to repair it without costing a small fortune? As one can see there are no usual cracks showing. We want to rebuild the motor and replace the 1.7L in our 1972. I have the 2-liter injection system and want to keep it mostly stock. We will have to replace the pistons and cylinders. Any recommendations on which ones to buy? I would like to end up with about 100+ HP. Thanks jjs3rd914    |

Here are some additional photos. Many years ago I did a lot of NDE and I still have some dye penetrant. While this may not be the best test for cracks in this application, its better than my old eyes. The first picture is the pitted chamber. The next is the other chamber that indeed shows the start of a crack(s). Jake has a good trained eye. The next two are of the other head.
By all the comments I suppose the one head is scap. I was hoping to be able to slightly buff out the rough spots (pitts) and use as is until the cracks appeared. Jake, if most 2-liter heads have cracks, does that imply that most 2-liter cars on the road are running with cracked heads, yet still operating okay? The cracks you see in this head, pitting aside, could it be used on a stock motor or is this wishful thinking and as pointed out, the head could become a book end! Thanks to all for the time to read and respond. jjs3rd914     |
