Default what compression ratio would this be?

With a 1969 427 bb standard bore what compression ratio will I be at with these 305 afr heads while using closed chamber standard size TRW L2268F pistons? The pistons have a .300 dome and the afr heads have a 119cc combustion chamber.

Love my AFR 195 SBC heads, considering the 305s for my '76 454 Suburban.

They must be available now. I ordered a set direct from AFR about a month ago. They said 4 to 6 weeks for delivery. Ordered them assembled along with a few other parts... total damage $2239.00 plus $55 shipping... Ouch!!
