Default S&S Super Stock 883/1200 Conversion Head Kit - What's your opinion?

Hello,

I have a 99 XLH 883 Hugger that has been converted to a 1200 by boring out the original jugs. It has S&S 1200 conversion pistons, a Super E, Andrews N2 and RB Racing LSR pipes. It still has the stock heads and valves.

So I've been considering having head work done on the original heads but I have hot found anyone in this region that I trust yet. So another option might be to buy the correct S&S Super Stock head kit (SKU 90-1310...maybe?).

Next comes consideration for the cam. So should I go with a S&S cam to go with this head kit and if so...which one? Maybe go to an Andrews N4?

I'm new to the forum and new to Harley. I have 16 years riding experience on Triumphs and BSA's but I always wanted a Sporty. So now I have my dream sporty to tinker with.

Thank you for any guidance.

I've never been overly impressed with S&S heads in stock form.... You would need different pistons as well since the combustion chambers are different. If you are looking for an excellent performing bolt on combination I would recommend buell thunderstorm heads with matching pistons and either Andrews N4 or SE .497 cams. That particular combination with proper tuning (and good carb, exhaust and ignition) will make between 85 and 90 hp easily (I believe mine made in the ballpark of 89 hp with that combination. You can get the thunderstorm heads and matching pistons on ebay from St.Paul HD for around $700. I haven't personally seen anyone with bolt on S&S heads make near that power. Good luck with whatever you choose and enjoy it!

Thank you for the Buell tip. I have read a number of forum posts under the keyword search "heads" and I learned a lot. So needing different pistons is not too surprising to hear. Now I need to go study up on Buell heads and pistons. Thanks again...

We can do wonderful thngs with your stock 883 heads. Our stage 2 headwork using 883 heads has been known to pull 95 hp if the rest of yor engine is built to match. Best part is the cost for stage 2 light headwork using your 883 heads is only $800 and you can keep using the same pistons you have installed now.

Hmmm...now this is sounding good. Can you be a little more specific about "if the rest of your engine is built to match". I admit this project was not well thought out. In fact it sort of dropped out of the sky. But I'd like to keep some of my current add-on's such as my RB exhaust and my Super E. But...I do have an open mind, just not an open wallet. Thanks for helping. You are giving me hope.

Let's see. S&S heads 2.00 inch intake valve, 1.605 exhaust, Buell thunderstorm heads 1.810 intake, 1.575 exhaust. Pluss S&S lets you go to an over .600 cam if you want as well as a two inch intake manifold. Do the math. However porting your basic 883 heads can give you a significant performance leap as well. Actually probably more bang for the buck.

Again...I'm just a newbie with a lot of research and no experience but from what I've read on this forum (which I consider an extremely valuable resource) and other places, the NRHS Stage 2 Light job on stock 883 heads looks like a very cost effective way to do what I want...which is to surprise a few big twins and some big block 4 wheelers. Just for fun. That solution is looking pretty good.

it will be a few weeks yet, but i will have a dyno sheet for you to look at. i went with the 1250 kit with 10.5:1 compression pistons, stage 2 light headwork on my 883 heads, .536 cams, nrhs hurricane intake, and the d&d bobcat. im using a power commander 5 for my tuning.
