  • Time for a block skim and raised compression ;)

  • That’s cool! Remember, increasing the bore raises the compression ratio anyway, worth calculating what it will be. Also, I always measure piston to bore clearance just to check the hone job is good.

    Get the head looked at when you have it apart too, valve seats and maybe a little gas flow? Should rip!
