you need to work out your compression ratio based on the bits you're putting in the engine.

As a guide, I am looking at cast 10cc omegas in +0.020 (1293), with the 0.040 deck height, BK450 head gasket and 28cc head chambers giving me 8.0:1 (my maths is not guaranteed). I'll be having my block and head skimmed (just a clean up), so that might go up a little.

In out van, we've run 15psi regularly and more at times on around 8.2:1. It hasn't blown up yet, but we've not had the head of yet (coming of in a few weeks)...

I think you've misread mate, it says 8.0-1 for 20+ psi. :)
