I've got a 103 with Crane 570 lift cams, took it apart to put in the SE cam plate & tensioners this fall at 68K miles, everything looked great including the cams & lifters. If you use quality parts & maintain the bike well you shouldn't have any problems, quit worrying & ride.

Guys, thanks for all the replies! The bike runs strong, just need to tweak the map a bit. I will be doing this in spring!. Regarding the question about why "Stock B lifters" I was told these are very reliable. Is that not the case? And is this the weak link in the build?

"cheap, fast, or reliable you can only pick two" LOL

I always liked the one, "The only thing faster than cubic inches is rectangular dollars."

You get to choose two.

It's an old joke, but oh so true.

i have a great combination in my 103, and i also believe that there is a happy meeting point between longevity and performance as long as you don't go overboard. i'm using the hd 259-E cams with .579" lift, and 10.75 compression ratio slugs. it's a comfortable and fast bike, for a dresser anyway.

Recently I have heard that the high lift cams like these 585's are hard on the valve train and may cause another failure.
I am looking for some feedback from you guys that run these type of cams and looking for opinions if I should be redoing the build, and if so with what?

If the engineers at HD thought they could wring out more ***** without sacrificing reliabilty don't you suppose they would have by now?
Stick with exhaust, intake, Power Commander or similar and external components.

HD is choked by EPA regulations, our changes like A/C's, exhausts, cams & a decent tune kinda "bend" those regulations!
