HELP!!!273 rocker shaft and rocker install

Which way do the rocker shafts go on a 273 solid cam? Also I have one rocker that is tight against the pushrod and valve and still have about 3/16 of inch to go before the shaft is seated, the cup of the pushrod is hitting the rocker. I am using a ISKY e-4 cam and stock solid pushrods. Almost thinking of giving up the solid and going to a hydraulic, any suggestions for a complete kit (cam, lifters, pushrods, rocker shafts, and rocker arms).
Thanks
Aaron
