Can anyone tell me what the specs are for the SE 103 heads that are fitted to the CVO bikes and are in the 103 kit for the 88" motor.They come with the 253 cams,pistons,pushrods etc.I have a set that I got at a pretty reasonable price that I was thinking of putting in a new Road King so that I can retain the warranty. thanks,

I also have a set of those SE103 cvo heads and i love them they look fantastic
and they run great. now to answer your question go to the hd web site and look
up the SE pro racing parts then check out the SE 103+ heads they are almost the
same as your heads except yours and my heads have slighty smaller valves both intake and exhaust. I am running the 103+ pistons with SE 258 cams a SE air breather
and cobra speedsters exhaust. I never had it dyno tested but i can hit 70mph before i hit 3rd gear and it tops out around 117 to 120 mph

 

hi Kevin,

are you using the flat top cast stroker pistons with those heads?
