I don't think the gt 500 lower will bolt onto 4v navi heads. I think you need the gt500 heads or cobra heads.
The few 4v s/c setups i've heard of, use modified cobra heads and adapter plates to mount to a modified gt500 lower (i think). Unfortunately the guy I know who had S/C'd 4v is now dead. So that's not much help. all this 4v stuff is confusing, but id like to fully grasp what fits. I'm sure myfx4 will tell us all about it haha.
