now i'm not sure but 4th gen heads from LS2/7 don't fit on 3rd gen blocks like LS1/6 do they but someone at a shot was talking about building his LS6 and putting L92 heads on it... is that possible i didn't think u could mix 3rd gen and 4th gen parts

edit: n/m i found my answer it just needs a slight adaptation

 

Care to explain?
