Difference in heads?

[A96LT1355Z28]

I tried a search but wasn't able to find any awnser in the 600+ responses! A friend of mine has a C3 Corvette with a powerless reman engine. He just got a 350 from a mid 90's truck. He said it's a Vortec 5.7L and asked what the difference was between a normal SBC and a Vortec. I told him I believe the block is no different than what he's got and I thought the difference was in the heads but I couldn't say what's different about them. It's has centerbolt calve covers, and it was free, that's all I know! Sorry for the newb question, I'm not familar with much of anything but LT/LS engines! :oops: :)

Thanks,

Not all centerbolts are Vortec's. If it is, it should have 4 bolts per side for the intake to head mounting instead of the more common 6...

OK, thanks I'll find out how many intake bolts there are. If it is a Vortec is it better, how?

If you look in the intake port of the Vortec head VS a STd head the vortec had a point in the runner to swirl the air before entering the chamber, other then that just the valve cover bolts.
