I know that all 1G and 2G cylinder heads can be swapped and etc BUT....is there any difference in the non-turbo heads with the turbo cylinder heads? I would assume not, but theres always room for error!

Stay away from the 2g heads unless you like porting. The cams in the 1g turbos are better than the 2g's and the NT's also. The 1g NT head will work on a turbo car.

Well, i have 2 sets of 1G Turbo cams sitting right here in my garage, so that would be an easy swap
