273 Engine set up I'm thinking of going with, let me know what you think

"If they would all detonate no one would be happy." Not sure what you mean by that? The 9.6/1 is your final ratio I take it. Do you run 87 octane or CAN you I should ask? Is the performance ok? Not sure what the timing has to be with these given my cam selection. Is it somewhere around 8deg before tdc?
