easy way to tell if i got a solid cam or hydraulic?

is there a easy way to see whether i have a solid or hydraulic cam? it has the mopar peformance 1.5 rocker setup.

also, how close to the head can the pushrods be? mine are aweful close, if not touching.

i hear a rattle when running, and pulled the v.c, put the number one cylinder to where the valves were closed, and there was gobs of play.
