Compression ratio what to do??

Ok, so what I'm reading here is that my 1971 340 stock motor was around 9.3>9.5:1 at best from the factory. I used the Fel-pro .039 gasket on a rebuild with the TRW 2316's so I was down even more. With just a .484/284 hyd., dual plane, 750DP, small hdrs stock 2.02/1.60 heads that motor showed 301 on track crank hp, and later with bigger carb/hdrs/cam 368hp, same CR.
The OP won't be much less CR than I was as is, the 703 Lunati Voodoo is more lift/less dur than the purple if I read it correct for better DCR so I cannot see its worth the expense of going to 10:1 for a few hp myself, obviously CR has all the benefits mentioned but its not everything, the Heads are, not so important on a street build...my2c's
