No, the GN 3.8 is a completely different engine, the only thing that fits are other 4.3 heads, go figure all the syclone/typhoon guys use ported vortec heads, its either that or something like $2500 for the set of alum heads available for them.

full on track cars can take a lot more liberties with shit than a street car. bell bottom kits and crazy wheel fitment look cool sliding on a track, but when i want to drive to taco bus, im going to ruin all of that shit. so it just doesnt work for me. function over fashion.

GN heads suck anyways, like said use vortecs or you can find aluminum heads for around 500 if you look hard enough. i have a set of bowtie 23 degree heads for my new turbo 4.3 sitting on my engine stand
