Although my intention was just to have the heads freshened up to be on par with the overall restoration Matt at Leistung along with 5thscaleracer could not help themselves and had the guy that works on their Cosworth 16V heads spend some additional bench time with them. I'm not sure what this will translate to in terms of a power gain but I guess it is proof there is some room for improvement with the M119 heads. Anyways looks like CFM was increased roughly 15% at top lift. I would love to hear some opinions from the heavyweights on the board (good or bad). Just butt dyno gains or real numbers???
