I just ordered a Stage 1 RCR kit for my 99 Sport. Rick mentioned that a head swap would also increase torque/horsepower. I forgot to ask what the compression ratio is stock and what his shaved heads would increase the compression to. I imagine anything over 11:1 would require 100+ octane. What is the stock compression ratio and what are most of you guys running when you shave the heads?? Thanks in advance.

 

You can swap heads with HPD's cool head from RCR, you will get better cooling/ performance and o-ring sealing, plus it looks realy good polished. If you get the 12:1 dome you can run pump gas or when you get the need for more power you can jump to either the 14:1 or 15:1 domes and run your favorite race gas.
