Rebuild kit for TC heads?

Rebuild kit for TC heads?
Does anyone have any experience with rebuilding twin cam heads? I am unable to find any type of rebuild kit and I am looking to rebuild my heads and replace the rocker assemblies due to a progressing clacking type noise similar to that of what rockouts are used for.
I already had my bike dyno tuned so I don’t want to do any real head work, just rebuild them with one parts. I’m on a 17 lrs with the se 117 kit.
Im also wondering if I should use stiffer valve springs (I believe them to be the culprit but not 100% sure). It was suggested I use stiffer springs due to the se 259e cans that came in the 117 kit. I now have 25k miles on the bike. Any advice or suggestions are greatly appreciated. Thank you.

yea I tried rockouts but they didn’t help. I thought about installing one in each hole instead of just the two that they call for but I wasn’t sure about it so I didn’t. I’m just looking to replace everything and don’t want to piece it together if I don’t have to. I know the description calls for stiffer springs but still wanted to see what all of you had to say about it

No offense -
I can tell from your post you don't have a clue.
That said -
You need to chase the right problem to fix your tic.
If you have a sort of rocker lockers installed, then it is probably your lifters that are at fault.
probably.
I recommend you take it to an expert and get a better idea of what the noise is B4 you start throwing money at a perceived problem.
You don't need springs unless you are going for a performance High lift cam.
With only 25K on it the valves should be just fine .

Yep. No "kit" for a head rebuild. You take it to a machine shop and tell them what you want...or better yet supply the parts you want. The parts that the shop will check/replace would include:
valves
springs
keepers
guides
stem seals
seats
The "kit" you need would be a top end gasket set, to reinstall the head when the shop is done with it.

i appreciate you trying to help, but telling me I don’t have a clue doesn’t add any more assistance. No offense taken. Anyway, since I’ve been a master tech (auto, motorcycle, and hd truck) for 9 years now, I did what I always do which is break out the stethoscope, however in this case, regardless of where I place the stethoscope the noise doesn’t get any louder or clearer especially when I have to rev the engine slightly for it to be loudest. It’s slightly louder with the stethoscope on the rocker box or hear than lower in the engine. I installed the rockouts when I replaced my lifters about 2k miles ago.
At this point im not looking for advice on how to diagnose the problem, I’m looking for input on which products others have had success with as I have never had to rebuild the heads on any of the twin cams I’ve ever owned. I asked about a “rebuild kit” meaning a complete package of valvetrain components. I asked because I have not yet familiarized myself with valvetrain component options/products. With 259e cams I believe it’s nevessary to go with better valve springs. When I installed the kit I wasn’t worried about it because I had planned on doing headwork at some point. I don’t plan to do headwork now. I’m not “throwing parts”, the noise is coming from the top of the rear cylinder and I’m choosing to replace everything while I’m in there for two reasons, 1-it’s only about 250 for everything from hd, 2-I ****ing hate being stuck riding my wife’s street glide while mine is down.
So i thank everybody for their help, but I am simply looking for experienced individuals to tell me what products they recommend and what they’ve run on their bikes. Just as I’d ask others for suggestions on hardwood floors if I had never replaced them before.
again, I’m not very educated on who makes better quality valvetrain components. I’ve rebuilt heads at work a few times but I’ve never done it on my Harley. But I also never installed a 117 big bore kit, until the day I did. It’s all the same **** to me.

Really?
OK, you are new here and I don't want to **** off anyone again ...but a master tech knows there is no such thing as a valve job kit!.
Truly.
If your cam specified HIPO springs they should have been installed, then.
Lifters?
What kind or who?
Some are crap out the box.
pushrods- whos? you have to know the thread count to get the preload correct as they are not all the same.
Send your heads to Baisley with your rockers and they will re-engineer it so the HD valve geometry is correct.

i was a dealer tech for 8 years and just switched to one of the big 3 working on preproduction engines...how am I not the mechanical type? Cause you think you have everyone figured out by their posts? Try reading my write up on my 117 install on here
