All good! And for that matter I never 'plotted' the used set of -1 offset that I bought, they are stamped 1.6. The pic i showed was my set of SR-offset rockers just to show the undercut. I just assumed you were more involved and aware of the build details of his motor, asked for posterity. Yes, makes you wonder if his were actually 1.6.... and his spring pack is set up more for 1.5 and less lift etc. oooof!
