bought used motor need advice
 

98 sierra xcab 4x4 5.7 vortech. i bought a used motor with about 100k on it. it had good compression, the fluids looked good, it sounded good also. i am going to do a partial rebuild. new oil pump&pickup, main seals,valve gaskets, intake gasket,water pump,crank bearings maybe.
other small things to like thermostat, etc.. is there anything else that i should really consider to replace before dropping it. id like to have heads machined but idont have time.any feedback would be appreciated. thanks jedd
