no vortec heads. its the 350 gm goodwrench motor. looks like he swapped intakes off his old 305. and he added a holley carb. i bet he got it as a longblock no accessories. the intake looks a ton older then the rest of the motor. the intake was missing half the bolts lol. anyways it ran fine before i pulled it from the parts truck. So will it still be okay to let a little bit of the crap fall into the heads???
