What's the compression ratio going to be?

IMO, I'd try the TR-55's first and step to the TR-6's if they are being blown out.

Not sure what they change the compression to. Drop a post or search the Internal Engine section.

With the near stock compression I'd stay with 55's. I'm running 11.1 to 1 and run TR6's gapped about .042
