All the SE heads, with the exception of the Pro Kompressor or the MCR heads, have big chambers and will not produce the compression those cams need to really perform. The MCR and Pro Kompressor head chamber volumes are too small and will put compression at the upper end of the range for a street motor; wouldn't recommend those either.

You would be better off with a new set of OEM heads and a .030" head gasket than with any of the SE heads. I know, doesn't sound right but it's true.

16500013A Screamin Eagle Pro CNC heads. They run about a grand, purchased outright. They have the 85cc chamber, and are machined for ACRs.

16500067 are essentially the same ones, on an exchange basis for about 600 bucks, with your old heads as cores.

Just get stock ones and have them worked. Not to sure you will find a bolt of with that cam. It doesn't want larger chambers it wants more compression.

The CNC factory heads I was referring to are the stock castings that are worked over by Wegner for Harley. They have the 85cc bathtub chambers, not the 95cc CVO chambers. I wouldn't pay a grand for them, but the OP mentioned his dealer is buying his new heads.

Gotcha. I read your post to fast. That would work if they will fork out for them. I guess we don't really know the circumstances and we don't really know how bad they actually feel about it. The op might get pretty lucky if they feel pretty bad..

Boogaldude is on top of things; I overlooked those heads in my previous post. They showed up in the 2011 SE Performance catalog as 16500013 for $799. That PN doesn't produce any results on Zanotti's but 16500013A does but Zanotti's price is $848; doesn't make any sense. Doesn't matter if the dealer is paying for them; good way to go. I don't believe they come machined for ACRs. I would also have the dealer install them with a .030" head gasket to optimize the compression for those cams. Cam lift is limited to .585", so you are OK with the 555 cams.
