Did you add 15 degress to the 050 timing for your dynamic compression ratio?.

I did add the 15 degrees on the KB site but not on the Wallace site KB site said 825 to 1 and the Wallace site siad around 9.0 to 1, if I remeber correctly. I'll check both sites again and write the results down this time Thanks to all for your input. I'll probally swap the heads and run the motor on pump gas again just to learn from the parts differences and the performance gains or losses
