Drill another hole and tap it to accept a 0-15 psi pressure gauge. Back off all intake rockers. Use a bicycle tire pump and attempt to slightly pressurize the manifold plenum/head ports. If you couldn't get any pressure built up to stabilize the gauge, wouldn't that indicate that there is lack of seal somewhere?
Great idea , wish I'd thought of it, don't forget to securely block all vacuum ports on the manifold.
