I'm starting a build based on a Tillotson 72mm block and was shopping for cylinder heads so I went to NR Racings website to check out what they had to offer. While browsing their "Race heads" section, I found an 18cc Honda UT2 head that peaked my interest. I noticed that "Milled .050" was selected by default and it confused me. Was it 18cc before being milled .050" or after? because the listing says 18cc head and .050" by default, one would assume it was 18cc after being milled. If I just added it to my cart and purchased it, I wouldn't receive an 18cc head, I would be receiving an 18cc head that was milled .050 and to me that's misleading if the end result I wanted was 18cc. I also noticed they had other milling options with no final "CC" of each particular option so I sent them an e-mail and here's what I got, then my reply, try not to laugh!.
