Alrighty then, tried to make some progress on crutches...got teh cam pulled....not suprisingly it's not an Isky...but it is a Howard. On the front is the stamped Howard(pretty sure anyway) and F6..and the back is stamped Z77...i checked the piston to deck and without having a degree wheel on there and good estimate is about .010 under the deck. These pistons have no dome at all, perfectly flat at the outer edges then machined inward in a slight dish. I'll try to get a couple pics up later tonight.
