Hi Dan, I must admit, I haven't seen every head design AMC used, but I have -never- seen an AMC head with pressed in rocker studs. I've got a few different ones here, including two different 304 bridged rocker versions, and none of them have pressed rocker studs.... I thought the pressed studs were purely a Chevy thing?
