88\' 350 tbi- centerbolt heads and intake for sale I just pulled these heads and intake off my 130k mile engine in favor of some vortec heads and intake. The valve seals in the heads probably need to be changed along with the valves because it smoked a little at startup. The intake is in good shape with the exception that some of the factory black paint has chipped away. Make an offer. -The heads weigh about 50lbs a peice and my zip is 70506 if you want to estimate the shipping.
