web cams

[SadSak]

Just wondering if anyone has had trouble flogging out buckets and cam lobes using web cams from Brock? Have just chewed out third exhaust cam and 2 buckets on 2000 busa with Brock big bore and web cams,apparently the cams come with heavier valve springs and we think that this maybe the cause of problem?
Have been told that stock inlet cam on the exhaust side will work but curious as to what other options are available?
Anyone have any suggestions?[/size]
