Re: 69' amx
The 558 S/S head had the chambers completely opened up to unshroud the larger valves, accounting for much of the increased volume. The heads I had were completely polished , and came from the S/K Performance car . .........Kenny Freeman was instrumental in getting the 558 superceeded by the 291 casting ........AMC by that time could have cared less. ..........Tom
