One is 60 dollars more than the other. Why, what is the difference i can not tell? Also, it says it fits my 86vette but does it fit the cast heads or is that just for the iron heads. I don't know much about bases.

Oh I see, one is for stock heads and the more expensive one is for vortec heads. I couldn't figure out why the big price gap. Oh well.

It is pretty stupid for the difference to be that huge.

The 3860 will fit your car. The Vortec unit is probably much higher because the units sold per tooling cost ratio is a lot lower.
