yeah but the new style top end should still bolt to a 3.4 bottom end, maybe even a 3.1 since they basically mirror images with minor tweaks. its worth the hp gains especially since no one makes mods for these motors and the newer gm manifolds are getting really efficient on the 60 degree motors as the design fades out to the newer ohc motors
