Thanks for the info guys. I know for sure the casting number starts with a 387 not 397 and they do have 1.94's and press in studs. I had a book a long time ago that told what they were but it's long gone and Mortec don't show them.they have sunken exhaust valves so their early non hardened versions and luckily no cracks.Thanks again
