What would my compression be?

I have a stock original 350 in my 1980 Z28 and will be putting on a set of 492 double hump heads. Does anyone have an idea on what my compression will be approx.? Thanks.

Just a head swap from 76 to 64cc? Depends on the head gasket, but around 9:1.

78 Malibu. Inherited from my Grandomther with only 35K on the odo! 13.4 @ 107 with mild N/A 383. With Weiand 142 blower installed....... not quite so mild. Orignially shooting for 11.99 on street tires, but mid 12s appears to be the best it's gonna do. Too much cam, not enough converter and nowhere near enough traction.
