I'm considering a head upgrade for my 05 Electra Glide. I understand that 06 and up is a better head. Does anyone know where I can find casting numbers? Do I need to stay at the same displacement or will heads off a 96" work?
any head with 7mm valves & beehive springs (96") is what you looking for,the `07 up heads are the best(the 05-06 heads still have the small ex port).you will have to get the later int. flanges,their about 9.00 each @ HD
If you are porting the heads it makes no difference what heads you start with.....I prefer the older heads exhaust port as you have more material to shape the port like it should be shaped as opposed to being stuck with Harleys idea of an ideal port.
What are you tryin to accomplish just plain john? WHY are you pulling heads?
Answer these and maybe an answer more suited to what YOU are trying to accomplish can be answered.
I recently did cams, exhaust and dyno tune. I want more, so I'm scouring ebay for a set of 06 and up heads. I say 06 and up because I have read here on the forum that the ports were improved in that year. My heads already have the beehive springs if that's any indicator. I don't need them today, I just want to watch for a set should one appear. I can't afford new Fuel Moto heads or the like, so I'll find a good set of cores and redo them.
OK. The guys that asked you about heads are the head guys, so I would assume you received your answer.
My thought would be to try to get 07-08 heads and not really new ones like from a 12.
I could be mistaken, and I am sure Kirby or John will correct me.... my understanding is the newer the more likely there will be terrible casting crap from the factory.
You could mail in your heads and, for around $500 ish... or possibly less, you could have a nice set of Street Ported heads, all the while using your own heads. Or... folks like Kirby and John will do 'core charge' heads. They will charge you for the heads, along with the porting, but once you send your original heads back, and they meet inspection, they will refund the core charges.
That could save you the cost of the new heads.

I'll keep that in mind, but it still doesn't answer my casting number question
the casting number is on the top of the heads.xxx99 early model, xxx06 late model
Ive got a set of 05 ported heads by kirby ill be selling here pretty soon
