Did you realign the valves before you adjusted them? I'm asking because I didn't. I just tightened the Pushrods and its more quiet but I still hear noise and a rattling sound. I thought it was the exhaust manifold, but I tightened them. I still hear the rattle. It does, however, run great. I hit 113 mph on 5th while passing cars with out" trying" to reach that speed.
On 3 turns right now and all new seals on the tubes... Went ahead and put new lifters in because I didn't do that when I put in the cams hoping that helps quiet it down...
Took me about two hours total but when I started it up the front retainer clip popped off the front tube POOF oil everywhere...
The clip didn't seem to want to stay put... I messed with it and finally was able to run it on the lift for about 15 min... hope it stays put...
Wondering if anyone else has had that pesky clip issue???
anyone ever safety wire those things? (Im an old motocrosser)

Hey Motoman! Got your ears on?
Not sure if anyone is still following this thread, but Hannum's HD just installed these V&H .575 cams in my 2014 Fat Bob. It's a stock 103 except for V&H Short Shots, S&S Intake, and V&H FP3 Tuner.
I based my decision to go with these cams because A) I figured that V&H would have an excellent map for their own parts, and B) after watching your videos, Motoman.
So thanks for posting your info! I wont pick the bike up until Saturday, but the guys at Hannum's were loving it. Said the map V&H gave them was spot on, said it's mean now. Power everywhere.
The V&H site doesn't have much information about those cams so I contacted the V&H Race Shop. Raphael Paula did some digging around and sent me some good information.
Basically these are the cams they developed for their +30 kit.
I was playing with the Big Boyz Twin Cam Compression Calculator, and I think I could get away with the 79cc S&S Super Stock heads listed for my bike. I think I'd have to use a .045 head gasket though.
But, I think my next move will be sending my heads to Zippers to get them ported and shaved to raise the compression to around 10.5 or so. Zippers is less than 2 hours away.

Hello Anthony,
The email below has got a ton of detail. I hope it helps answer your inquiry.

The 107" piston kit was developed to offer an average compression ratio 10.25:1 depending on your cylinder heads. My studies have found that stock cylinder head combustion chamber volume can vary anywhere from 84-88 cc's . Based on the 88cc combustion chamber volume you would be at or near 10.0:1, if the cylinder head combustion chamber is closer to 84cc then you would be at or near 10.3:1. Most of our test cylinder heads were around 85cc's which = 10.25:1
I personally would machine the stock heads to get my compression ratio in the range of 10.5:1- 10.75:1 for optimum performance. Remember fuel quality is key when raising compression to a number closer to 10.75:1, tuning is more critical as well.
Cam specs: .575" valve lift 240 duration Intake 240 duration Exhaust.
Intake Timing at .053" 20°BTDC/40° ABDC
Exhaust Timing at .053" 45°BBDC/ 15°ATDC
Overlap 35°
Intake Lobe center 100°
Exhaust Lobe center 105°
Lobe Separation Angle 102.5°
This camshaft works great with a stock 103" engine all the way up to 110".
Stock 103" 98HP and 106TQ
107" engine with 10:75 compression 112.76HP and 120.46TQ
V&H ported heads with 1.9"-1.610" valves110" Engine CVO heads 10.75:1 Comp ratio 122HP & 118TQ
We developed this camshaft kit as a bolt in to allow customers to use without doing head-work and the need for better valve springs. These are the basis for our 30+ kit we are offering for sale in the near future. I will add that these cams work well with higher compression and larger displacements as well.
I have attached some dyno charts for you to view and to see what I have witnessed from testing of these components.
Below you will see the Dyno attachment 30+Streetglide which is a stock 103" FLHX with stock heads, stock compression, V&H Powerdual exhaust with O.S. 450 mufflers, V&H Vo2 Air cleaner kit, V&H Adjustable Push-rods, V&H 575" Camshaft kit, and V&H FP3 Fuel Pak tuner. 3 dyno runs showing HP and TQ. Note: All of these DYNO runs are in 4th gear, so technically when runs are done in 5th gear you will see an additional 2HP and 2 LB-FT TQ increase! This is done for a safety margin on our claims along with keeping tire speeds at a realistic level during all of the testing performed. (Thousands of DYNO runs = extreme tire heat and wear)
Dyno attachment 107best is a dyno test that has our 1.9"-1.610" ported heads and 107" Pistons with a compression ratio of 10.75:1, Tuned with V&H FP3 Fuel Pak and Powerdual Exhaust with O.S 450 mufflers,V&H Vo2 Air cleaner kit, V&H Adjustable Push-rods, V&H 575" Camshaft kit.
Dyno attachment 1102-1 dyno chart test with 10.75:1 compression ratio 110" flat-top piston, our ported heads with 2.0"-1.63" valves, V&H Stainless 2-1 high output exhaust, V&H Vo2 Air cleaner kit, V&H Adjustable Push-rods, V&H 575" Camshaft kit, S.E 58mm T-body, 5.3 GM/sec injectors. I hope this helps you with your purchase decisions, if you have any further questions please don't hesitate to ask! -- Raphael J. Paula | Vance & Hines

Does anyone have any experience with the Vance & Hines 575 Performance Cam?
I have been looking at cams and cannot find any reviews on it...
I already have the radius 2 into 2, FP3 and upgraded air filter...
What about the quickie pushrods... S&S or the tapered Screaming Eagle ones?
Thanks in advance
