You could install a pair of 351-HO or Boss-351 aluminum rocker covers in place of the steel ones. Our Pantera came with them plus a date-stamped Boss/HO baffled oil pan but not the HO heads. They were included on those optional engines from Ford and are finned black wrinkle finished with no cast logos. Only a 1" flat area in the center for very small Ford steel spark plug wire separators. All this might even be 'stock' if ordered from DeTomaso back in the '80s! Not sure what was stock on an Amerisport GT5-S. Peter, how many did Kirk build?
