2013 Screamin' Eagle Ported XL 1200 Heads Part #16500164 Cam Choice Help!
"2013 Screamin' Eagle Ported XL 1200 Heads Part #16500164 Cam Choice Help!"
Hello Everyone,
I'm new to the Forum.
I'm the proud Owner of a 2005 XL883C. I'm having it converted to a 1200, with HD Dealership Parts, at my local Dealership. It goes in next week...
I have purchased the, Brand New for 2013, Screamin' Eagle, Ported, XL 1200 Heads, Part #16500164.
I'm considering Stock XL 1200 Cast Flat-Top Pistons over the SE High CR Pistons, because, I'm leary about having a Street Bike w/a CR over 11.3:1. Though, the idea of Forged Pistons, does sound good to me; my Mechanic at the Dealership says that the Forged Pistons are noisey, and are not required for Stock Compression Ratios, and the cost is about half for the Stock Pistons. Note: Any thoughts are welcome on this. I'm having the Dealership Bore and Hone my existing Cylinders out to Stock 1200 Specifications.
My Bike is a everyday rider. I don't drive a car...
I live in a congested California City. I want more Streetable Power out of my Scoot...
Should I stay with a Stock CR of 9.7:1? That's the CR I will have with the 59.9cc Chambers and Stock Cast XL 1200 Pistons.
What would be the best Cam Set for this Set of Heads and a Stock CR of 9.7:1. These Heads can handle a 585 Lift, and are ported...
I was thinking of the SE 575, so I can take advantage of my Big Valves and SE Spring Set... But it looks like they require a Higher CR...
What Cam would best benifit from my proposed Set-Up? That's my Question...
Here's the info on the heads that I found on the net:

Cylinder Heads SportsterŽ
CNC Ported Heads offer a cost-effective approach to
upgrading the performance of your motorcycle. The intake
and exhaust ports are meticulously machined for smooth
surfaces, improving the flow characteristics of air and fuel
in order to provide enhanced performance. But it doesnt
end there; the proven stock valves rest in reshaped valve
seats to further improve flow rates. The combustion chambers
have been machined for smooth surfaces and feature
a blended radius on the bathtub edge to reduce detonation
by eliminating hot spots and promoting improved combustion.
The head gasket surface has been milled to maintain
stock combustion chamber volume (59.9cc), which results
in stock compression when used with Original Equipment
pistons. Compression can be increased with the installation
of Screamin EagleŽ high-compression pistons. Heads are
assembled with Original Equipment valves and high-performance
valve springs that support cams with lift up to .585."
CNC Ported Heads are available as a complete factory assembled
kit or your new motorcycles low-mileage heads can be
updated to these specifications. All EFI models require ECM
calibration (priced separately). For race application only.

My opinion is don't waste money on those heads if you are staying with stock compression. Those heads flow and need a big cam to take advantage of them and with a big cam and long durations you need compression to avoid a soft bottom. If you are wanting to keep compression down why not just get the 1299 kit that comes with stock 1200 heads? Or get the stage 2 kit that keeps the stock 883 heads? Better yet, get the Hammer 1250 kit.

First Build Option:
After reading up on them, it sounds like they were meant for the SE 575. Does SE make 10.5:1 CR Deep Valve Pocket Flat-Top Forged Pistons for my year (2004-06 XL1200) of Bike? If so, can anyone give me the part number? This is the Cam Set that sounds interesting to me, out of the SE Cam Sets...
Or, does anyone know if Wiseco makes a 1200cc Forged Flat-Top Piston that has deep valve pockets that would yield a 10.0:1 or 10.5:1 CR with my Heads 59.9cc combustion chambers? My HD Dealership installs Wiseco Pistons, too. So, they would have to be SE XL 1200, or Wiseco Pistons.
Second Build Option:
Does anyone have any knowledge about downgrading the valve springs to the stock 883 springs in these heads? I understand that the stock 2005 XL883C Valve Springs have a 550 Lift. Could these be used instead of the 585 Lift Springs that my heads come with and High CR SE Pistons, so I could save on having to buy more hardware right now, and just use my stock 883 lifters, rockers, cams, and Stock Cast XL 1200 Pistons and have a 9.7:1 CR? I had to buy shorter pushrods, anyway. And, then later upgrade if needed or desired?
What do you guys and gals think?
Note:
I have a 2005 883C, it has a Dynatek Single Fire Ignition, Accel Single Fire Super Coil, Wires & Plugs, Screamin' Eagle Air Cleaner W/K&N Filter, CV Performance CV40 Carb Kit, 45 & 185 Jets, Cycle Shack One Piece Shorty Duals W/Removable Baffles.
I have purchased for my conversion a Set of 2013 SE Ported XL 1200 Heads, Shorter Pushrods, XL 1200 Pistons (might exchange for forged flat-tops), & 04 883 Big Fin Cylinders that my HD Dealer is going to have bored & honed to the size of the Pistons I get. And, undecided on Cam Set (SE 575 for the High CR Setup & maybe SE Bolt-Ins 497 Lift Cams for my 2nd Option).
I'd really like to setup my Bike so I can upgrade it if desired in the future. But, it seems that I have to decide which way to go right now...
Suggestions?

Correction, 98 HP.
I started with a Stage 1 2008 Nightster, 1200 and added:
SE CNC PORTED Heads
SE Hi Output Cam .575/.575
SE xl1200 Hi Comp Pistons
-pushrods, gaskets etc
-dyno tune with SEProST
Comp Ratio 11.3:1 and runs fine on 91 octane
Work with the dealer on pricing. I got mine 15% off with no tax (bought out of state).
fwiw the dyno tune took it from 90 to 98 hp
My recommendation: With what you have in mind you definately need the hi comp pistons. It will make you smile. Hang on!
And, believe it or not,the higher compression makes the fuel milage go up.

That is the kind of info that I waslooking for.
I have purchased the WISECO,10.5:1 FORGED PISTON KIT, for 2004-06 XL's, #K1746, for my 883-1200Conversion. I'm going to have my Cylinders Bored & Honed to the sizeof these pistons.
This along with my SE Heads, I thinkI will have a 10.7:1 CR... Does this sound right?
What's the best Hot Cam choice forand Street Bike that's ridden daily?
I'm thinking of the SE 536 or SE575...
Also, are the stock rockers ok withthese cam choices?
Also, did you change your stocklifters & pushrods out?
And, does anyone know of a greatplace to score cams?

on my 2008 I have the SE heads with the 11:1 comp , with 575 cams , adjustable push rods , SE roller lifter and rockers .. if you go with the 575 cam is more for the top end rpm 4-7 grand , I don't know how the cam reacts with the lower comp. , but with the comp at 11:1 there no low end is lost .. had this for over a year with no issues with motor , just the exhaust bolts come loose...lol , invest in a oil cooler , doesn't help much sitting but sure does while riding.....

Hardly any 1200/1250 need compression releases. Even over 12.1 I'm really curious what the corrected compression ratio is with the 575 cams.
