Recently acquired a 67 conv.with a 200 6 and wondered if any one has used or is useing one of the alum heads I have seen? Have not kept up with any of the newer part for the 200 since I quit working on the 66 about 20 years ago.any info ro improve the car would be appreciated. Have toyed with the thought of trying to use the turbo and carb adaptor off of a buick sport coupe that has been sitting for a long time. Any thoughts ,does any one offer a package or parts to do this on a 200? Again any help offerd I thank you for it.
