Looking for some input on 360 LA build

At 65cc, 68-70 isn't far away.
Ex. 62cc ends up about 65-66cc after chamber work. I'm not sure what so bad about being a hair higher. What's the cranking gonna end up like.
I'm not going to do fuzzy math atm.
I'm not on the clock. Lol

I’m not feeling the OP has Head CC’ing tools. Maybe I’m wrong?

Well here are the cam specs....

I think you need a cam card with more specs than this to figure out cranking compression. But I don’t get a vibe this is going to bleed cyl psi. Others thoughts???
