Yes. You must use newer style rocker arms, not the rail type from the '68 heads. Pay attention to pushrod length. There are several threads on here that discuss issues involved with later model heads.

BTW, are you sure you have GT40 heads from a '93 5.0? The only 302 to come with GT40 heads that year was the first-edition SVT Cobra. Pretty rare engine to come across.

Sure they are not "P" heads? From explorers and a few others? GT40 heads will have 3 vertical bars on the end, while the P version had 4 bars. P heads are still a slight bit better than most stock 302 heads.
