318/360 heads,with thumper cam

I dont have a way of posting a picture at this time,the only way i know of would be sending a picture to someones email address from my phone,thats the only way i know of,other wise i cant.-Only one of the pistons touched an intake valve pretty good,all the others are smaller in size,i couldnt even see them before i cleaned the greas off with spray n a rag..also is the piston supposed to have a little bit of a rocking motion,like barely be able to be pushed by hand???
