351/393 no compression on #2and 3 cylinders

will a blown head gasket give me 0 compression if it's blown between these two cylinders?? I pulled the plugs and held my finger over the hole and turned it over and can feel the pistons pumping but get no compression. Pulled the valve cover and the valves are moving fine.

sounds right to me.....but I'm just a rookie......

yea thats what I'm hoping for. I think I just wanted to hear someone else say it as I would not be looking to deal with what else it could be.( motor tear down and replace pistons and or rings) THANKS

Pull the heads and find out......its the only way to be sure.

not necesarrily "0", but waaaaay low, and usually identical (or close to identical)
