I also, have based my engine build on that series of articles (it helped me choose a cam)
but I was a little farther into the head and cam upgrades that they did in later articles, with the same motor.

so do you have the peanut-ports?
and did you use the XE268H cam?

the reason I ask, is I am curious about the lower CR
