No, but they are milled, can’t remember what cc I’d have to go look at the paperwork, here’s my dyno graph

It was a guy fairly locally who did it for me. Does a bunch of hand porting for race engines. Worked out well for me. Car makes 545/513 to the tire NA through a Dana 60, 24lb Steel flywheel and 3.5” steel nitrous shaft. (Cars 3900lbs with me in it I needed the inertia of the heavy flywheel for it to 60’)
