compression ratio ???? 460

i have 1969 460 going to put sealed power flat tops 30 over in with c9ve-a heads with standard deck height does anyone know about what it will be i'm thinking around 11.1

With Sealed Power flat tops, about 0.015" below an OEM early block deck is typical, clean up the heads during the rebuild, you'll be approximately 11.25:1.

thanks man

got the machine work done took 00.8 off the heads engine guy said about 10.75.1 comp ratio
with the flat tops

I was going to say 11.5,but Paul is lots more experienced than me.
