most aftermarket retainers will give you more clearance but it's hard to say how much you will get..all you can do is put them in and check and see how much you gained..if it gives you enough, you're good to go..if not, you have to take the next step with the guides..

I put web 395/378 cams in my gen 2 busa last year. I ran them most of last year without any problems. I never heard any thing about retainer to valve seal clearance untill after I put them in. I thought I only needed to worry if I had 415 cams.
Now I hear their are problems with 395's. I never checked retainer to seal clearance when I installed them because I thought it would not be a issue. I will be taking it apart again in the next month or two and am now wondering if I should put ape ti retainers in.
