Does anyone know what kind of compression ratio would result with putting vortec heads (Casting 906)on a TBI 350 with stock pistons?

I'm guessing you might get to 9:1, at the most. But I don't know what compression the TBI motors came with factory, or the CC's of the heads.

Well got the old 191 heads off yesterday. Looks pretty decent in there. Lifters had zero signs of wear. So looks like odometer hasn't rolled yet.
