LT1 and L31 comparison question

I just have a quick question. The vortec 350(aka L31) has vortec heads on it obviously. Does the LT1 350 have the same vortec heads? Is the intake bolt pattern on a LT1 the same as the bolt pattern on a L31 vortec 350? Thanks

i'm no engine expert but from what i've seen the heads are not the same and aren't interchangable i'm pretty sure the coolant flows are opposite.
I'm sure someone more knowledgable will chime in soon
if you've got anymore questions feel free to not ask me (sorry i can't help lol)

Yeppers,Cobra is right.Question is are you looking to upgrade the heads you have??.

From my research the 'vortec' intake engines have reverse flow heads.
our TBI engines have 'vortec' head which are "high flow"

The LT1 heads will not bolt up to a Vortec block. Here is an article that you can read for more information.
