Doing is learning ,so hotrodfatboy I'd just buy a set and install them , you then have your own experience with the system ,and is yours not the most important opinion to you Sir. Let us know your findings.
Peace.

Wondered how long it would take to screw himself. I don't post much but I enjoy the posts that are posted except for this cat.
A bully & a know-it-all.
All I can say is " Don't let the door hit ya in the azz on your way out. "
And HotRod, I'm running the S&S rollers in my bike just because it gives me peace of mind.
20,000 miles & its all good.
There is a lot of good info in this thread except for the bs.
But that's gone.
Ride Safe,

Yeah Bagger i know how you feel... I actually though about that.... Sometimes it gets hard very frustrating which can lead to saying the wrong thing.. Sort of like the boss is on your *** and you call him out... Not good for anyone...
No I don't think I'm moving on.. It's more of an apology to all of you guys.... But maybe a time out for a while.. Believe it or not, this forum has truly become a part of my life.. I enjoy helping when I can and always love a good build thread or learning something new... Plus I didn't finish a couple of problems that I'm having with my bikes so I don't think it would be right of me to leave you all hanging.. LOL... Thanx Uncle Larry.. Ill be 
Thanx Harold, yeah definitely going to get them but will have to be a couple of weeks... And yes I will pay strict attention to the geometry. I actually got a degree wheel the other day so I can rotate my motor half the duration of the cam to see exactly how the roller tip lands on the valve.. should be fun... My biggest dilemma is 1.625 or 1.725 rockers..

its 1/2 the lobe lift not the duration and they also have 1.675 roller rockers - and that one increases the cam lift .025 thousands and adds 2* of duration yes the duration is also affected
the key using hydraulic lifter in this when adjustable pushrods are in play - is you need to know the exact spot the lifter is operating at and also the pump out or lifter top out - this becomes a thing as we have seen the rocker lift so hi at top rpms it hits the top rocker box and cracks it
reason for caution using on big lift and hydraulic lifters - two trains of thought come to play big lift short duration to trap as much static compression < big power on the bottom for go the top end power 5800 and on
long duration medium type lift cams are old school Harley power makers - the lap tops tell new builders to go big lift - gray hairs doing this go duration < its what we do -- valve spring tech for Harley is lacking and getting all of this correct is a balancing act you have to give in some places to get others

Wow, that would actually work. Granted you might have contact with the frame if your shim was thick enough, and I don't know who actually make a rocker base gasket shim, but it's the quickest and dirtiest solution thus far.

Back a few years ago I built an 88" Sportster. I was going to use Andrews N9 cams at first, but the head builder talked me into a set of Red Shift 630/585's instead so he wouldn't have to sink the valves as far into the head. Overall TDC valve lift was less on the Redshift cams vs. Andrews. Also, overlap is commonly longer with higher durations, for what that's worth on your build.
As this thread turns into KG's funeral...
Hotrod, stick around, eh?
KG was an enigma from the start. Seemed like he had some good knowledge/experience, but he had this bizarre practice of always sharing it in the most insulting, contentious, inflammatory way possible. When called on it, it was always "we're just having beers".
I had him blocked for quite a while. He replied to a bunch of my posts. In case you've never seen it, if someone you've blocked posts to a thread you're reading, you see a notice of the post, but you don't see the post itself unless you click the button to reveal it.
Eventually, I started revealing his posts. And occasionally, he offered something useful. I decided to unblock him.
I pity that guy. He strikes me as being desperate for camaraderie, but entirely lacking the social skills to get it. He's probably been that way his entire life. And it's probably been a very lonely life.
It was only a matter of time until things came to a head and he got himself banned. Anyone could see that coming 100 miles away.
The ban is for the best. Guys like that are toxic. I think we all noticed the up-tick in drama and contention that he brought to the Evo Forum. That stuff has a way of multiplying.
The funniest part of all this is that I'd very much like to throw down a few cold ones with him. Might end up with broken bottles all over the floor, but you know it would be interesting.
