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
would love to hear how this motor runs out when you get it all sorted out!!
