[1971455HO]

Hello maxilo,
I see you are new to the forum. Welcome to the all things PONTIAC world. The 1971 model 455HO engines are the ones with the 197 heads. The 1972 model 455HO engine has the 7F6 head. If you are interested in a complete 197 head engine, occasionally someone has one to sell. They are pretty scarce though and usually fairly expensive. I suspect you mean renewed (as in rebuilt) instead of reviewed. May be a little translation thing going on there. Where in the world are you?
