Putting the 360 together

I've been a little busy with work, but I want to get back to it next week. I and the machinist missed one problem. The pistons are flycut for the valves and you need 4 with the exhaust on the left and 4 with the notch on the right...I have 5 and 3! I called KB and they will send out a new piston if I give them the exact weight of the old one. So next week I'll pull one and have the shop weigh it. Ain't this hobby fun???
