Would the following spec be suitable for forced induction? and what CR would this give?

Bored 1380cc
Omega forged 11cc
Head - 26cc chambers

gary even with 28cc in the head your CR would be in the mid 9s
on a standard stroke
this would not give you much boost above 10 to 12 psi even with all the tricks on standard pump fuel

you want 18cc dished pistons and 28cc head this would give you 8.27:1 on a standard stroke

mind you with out number crunching a 76mm stroke will bring things nearer the optimum
