so i had a head gasket replaced and now i have no compression in the #4 cyl. i took it to another shop and they said it might be a bent valve, then they asked me if some1 tried 2 start it with the cams in wrong. and thats exactly what the guys that tried 2 fix it were doing when i was at there shop. so i told the guys who did the work and they said it could not b there fualt bcuz its a "zero interference head" and that the cams dont come down enough to bend the valves. BS or NOT?

As far as I'm aware, the 3SGE (Not BEAMS) has e "Zero Inerference" configuration. The valves don't extend far enough down into the combustion chamber to physically touch the cylinders. The cylinders also have a recessed feature in the top to avoid and interference condition, should the timing belt snap for example.
I've always been led to believe that low compression on an engine can be caused by shot piston rings? Maybe you should get those looked at?
