Can someone tell me if 99 Tahoe 350 heads will fit my 95 z71 350 , was told all I had to do was change gaskets..

 

It's not that simple.

 

They can work but the main thing is the vortec heads have a different intake manifold set up. Vortec heads have only 8 bolts to hold down intake manifold and the angle is different. You will need a vortec manifold adapter. The original manifold for non vortec heads have a 12 bolt set up.
