P&P Head Question

[DropTopPony]

I'm trying to figure out what my current and future Compression Ratio is going to be.
I have VT Engines Stage 2 PI heads. Anyone know how much material is removed from the Combustion Chamber(CC) during this process? I know i've seen it posted before and its not on their website so maybe someone else knows.

There's very little removed(I don't remember the exact amount but it's small). You'll see a drop in compression of .25->.4 of a point,depending on the head gasket you use. (Nothing you'll notice.)
