No, they won't interchange. Lt1 heads are a reverse flow coolant design, and L98's are a conventional coolant flow design.

That doesn't make someone automatically know an obscure fact such as this.
The heads generally LOOK alike. They both fit SBC engines.
It's a valid question.

Did YOU pop out of the womb knowing EVERYTHING?Or do you just THINK you know everything.

He may be running a modified LT1 intake on his L98. But, it isn't possible to run LT1 heads on a L98 block.
