Help! 360 with 302 heads no compression

Thats interesting. I didnt know that. Well i got the new push rods in. I got the drivers side done and started on the passengers side. With all my damn luck i pulled out the new pushrods and one was wrong. Someone must of put it in during the packaging from rockauto. I just went to a local dealer and got one. I adjusted the timing and did a compression test and got around 120 on all cylinders. Truck fired up fine. I just need to drive it around and work out the bugs. Thanks everyone for the help
