Not sure what the max lift is, but 574 cams will work with the stock springs with no problems....

Personally, I always go with new springs that go with the cam but it is up to each individual.

What cams come with springs?
I'm not sure what your speaking of.
My cams came with bubble wrap, instructions,a box but no springs.

As the post by Sadunbar indicates there is no need for new springs using the 574 cams on a 110.

With the latest style valve guides in the 110 heads, max lift per H-D is .596".  See attachment.

i read the attachedment  about the heads  ...did i understand correctly when the guides wear out the heads  are junk ? non rebuildable  if thats correct then i think i would be better off buying aftermarket  heads  then spending  money on these heads  on improving  flow,  cc 'ng etc ?

Actually, all they are saying is that they (H-D) won't be offering the new style guides in replacement sizes.  That doesn't mean you can't buy and install a better part from the aftermarket (which is probably a better idea anyway, considering Harley's lack of precision in their machining operations).  Guys like Don (Deweysheads) can provide a better answer, as well as recommendations about the CVO heads versus aftermarket for any specific applications.

The stock guides are a comodity part, cast iron, and they offer over sizes FWIW. The stock guides have a loose stem fit to prevent the exhaust valve seizing (not the root cause) as they did on the hotter running 07-08 bikes. The program replacement heads for these early 110 touring bikes have these guides fitted and I have one on my desk that seized anyway, the photo, and ripped the guide right out of the head in half. This head was fixed, no issue. They increased the press fit (which wasn't the root cause) and they also have an annoying snap ring groove that pulls metal when the heads are heated and guides driven out, actually that metal pull happened when they initially are pressed in, just get worse going back out. Have that issue dealt with now too. We porters have to work with what we are dealt for cards and on 110 heads, all of them for us, first order of business is to take out the stock guides and fit with the right press and stem clearance the AV&V bronze maganese guides. These can run a little closer fit for more valve and seal life and lower oil consumption.

Not for sale
For trade
1 black set for (2) front 06up OEM black castings undamaged not ported or milled.
Not expecting that to work because most don't have mixed sets, I happen to have bought many from wrecks and some are perfect (rears) and others got scrapped.
