What heads came on a 1993 Chevy suburban c1500 tbi. My friend said they looked like vortec but I don’t know for sure, i know the valve cover has center bolts if that helps...

They're likely 14102193 heads. OutInTheShop lists them as 1.84" valves, but mine were 1.94". They're widely considered to be one of GM's worst SBC heads, but the fuel mileage guys love them. Supposedly there's quite a bit to gain by porting them - but don't remove the swirl ramps. I ported mine and put them on a low-buck rebuild motor.

Aren't most Chevy small block heads either 1.94 intake valves or 2.02? That's what I think I remember hearing.... 2.02 was the big valve performance head IIRC.
