i am doing a conversion on my 883 and am looking to use xb12 heads. Has anyone ran or knkow someone who has run xbs on an xl?? I asked the harley shops and they couldn't tel lme

The front head motor mount is different. Why not use Sportster XB heads? They are the same heads as far as flow/performance.

Take a look here.

well I got some for a good price (400.00) and were just going to get them worked on. What would you recommend (work wise) from nallin. I am trying to build a budget rod and would love 100hp.

Any suggestion???

I just got done installing a set yesterday. The side motor mount will be tight. I had to bend it to make room for my choke cable. The bolts on the front motor mounts are a different size also. When I ask the Harley shops about putting the XB heads on mine they all said it couldn't be done. Come to find out that Harley makes a front motor mount to convert over.

You also need to drill and tap for breathers as XB heads do not have any stock

You are going to have to run some high compression and cams to get you close to the century mark. Going to have to get the heads up to at least a stage two with a perfect tune and perfect exhaust. Getting 100 HP is not easy, and very $$$$$$$$$$$$$$$. Its fun trying tho,good luck

morehp. what setup are you running? what kind of power does it produce???

100 rwhp is very easy, it can be done with all factory parts although the heads will need a good port job (NRHS). Your XB heads are a step in the right direction.

Easy? No way. Look at the dyno section with all the builds that have NRHS/other brand stage2 / stage 3 headwork and see how many of them hit 100 rwhp.

I have a set of silver XB head and the Short Push Rods you need to run them for sale.
