is there any difference between the 95 LT1 heads and the 97 LT1 heads....reason im asking is because im going to pick up a set of 95 heads to be ported for my 97 Z28 and i just wanna make sure they'll bolt right up without any mods

 

I think they are different casting numbers but they'll bolt up no problem....

 

The 94-95 heads are better for porting as they have a little more material compared to the 96-97s. And yes, they'll bolt right up.

 

sweet, thx guys

 

Try a "search". There's a thread from a couple years ago that has pictures of the two different castings.
