If you have a 65' block, (Alum), then the pressure fed tensioners will not fit in you cam housings. One option is to gut your old tensioners and make them into solid tensioners-what I did. The other option is to buy new tensioners and run the after market clamps that fit on the shafts and stop them from colapsing completely... humm... One option cost a three hundred bucks, the other cost almost nothing. I would like to stress that if you go with solid's you do need to make sure that you adjust then correctly, although; that doesn't mean you have to adjust them every day. I don't believe that properly adjusted solid tensioners cause more chain stretch than carrera tensioners. How can they? If there adjusted properly, there going from a little loose to slightly loose, with no real stress on the chain itself. You know, if you look up cam chain tensioner in the Porsche mech's dictionary their's own a two word definition:Job Security.
