Factory they were listed at 10.25:1 in stock configuration. I think they had 104cc heads on most of those engines. They have a 16.8cc dome on them. I have a new set lying out in the shop, just a stock Forged replacement piston from the 385-400hp engines back then. Came in everything from 4 door cars to Corvettes with 3 two barrels.

With a 119cc head (open chamber) you would probably be in the 8.8:1 ratio with a .005 DCV, .040 gasket. Zero DCV would put you at about 8.9:1.
