58b 58c heads

[Shep236]

Does anyone have any info on these heads?  

[Ohio HD]

I've never heard of these heads. Who makes them, and where are you getting the number?

[Deye76]

Panheads maybe?
Titan Motorsports have a head With the 58B# but are not Harley heads.

They must be better than 58a

They're twin cam heads guys.  Look at that link notice how it says 56c on the bottom of the head.  Because they're probably a dyna head not a touring like mine

Screaming Eagle CNC ported heads part number is on the box 16500015a .  Bob

Bob is correct that this is part number 16500015A. From what I can find on them, I would be more inclined to send my heads to a known head porting shop. Get more for about the same price. Below is a good place to start, all reputable shops.

And as you mentioned these probably don't have the front head mount for the 2007 up baggers. So if you have a 2007 up bagger, you might not want these. They list them for 1999 - 2017 Twin Cam, they would seem to exclude the 2007 up baggers.

Intake valve is 1.875", not much larger then OEM. Valve lift is limited to 0.585" maybe 0.600" will squeeze in, kind of limits the cams you might run.

Looks to be one head, not a set.

The kit part number 16500013A from the SE catalog.

Guys that was an example.  I have the heads listed in the title, those are bagger heads.  I bought them used with no valves for 400 bucks for the pair.  They're in good shape.  Was trying to see what the valve sizes were so I can order the valves from harley.  But I think I got it figured out.  Just seeing if someone had personal experience with the heads

[FSG]

Look at that link .....

surely you jest .....

So why didnt you say that in the first place instead you give a couple of numbers off the casting and a ebay listing. Once the proper part number is reviled it is determined there are S/E CNC ported heads. What size valves are in S/E 16500015A CNC ported factory heads would have been a lot easier and more direct question instead of a puzzle to solve first.   Bob

[Shep236]

I didn't have that part number 

[Ohio HD]

Actually you did.

[Shep236]

I didn't know what these heads were.  I found that head on ebay after asking the question doing my own digging around on them.  I had harley order me the valves for the heads with that part number I hope they're the right ones. 

[Ohio HD]

I'm not going to argue with you, but you supplied the ebay link with the head part number of 16500015A shown in the photo.

I would have ordered 1.900 intakes and machined the valve seats so they fit. You'll get more flow.
