Will a complet 305 intake tpi work on a stock 350 or do i have too change everthing out

 

Yes it will bolt right up. Getting it to work is up to you. The post '86 small block intakes however had a different bolt pattern for the four center bolts. You can use it on later ('87 thru '92) heads but you will have to wallow/enlarge/modify those four center holes. If you have an '87 or later intake set-up than it will bolt right up to any '87+ center bolt heads.
