I need new heard on my 06 twin cam 88ci. I found a good deal on a set of 103 screaming eagle heads. Will these bolt on to my stock jugs with no machining? And can I run my stock intake? The only upgrades I have motor wise is 585 s&s easy start cams. Thanks in advance

 

Your .585 S&S cams need to be at 10.5 compression, we actually prefer 10.7.
You'll need a piston with a large dome volume to achieve that.
That said, what is the chamber volume of these S/E heads?

Im not sure where to find that information, I contacted the seller to see if he knows and now I'm waiting on a response. Worst case scenario I would have to go with a set of dome pistons?

 

Ok the seller has no idea what the chamber size is, but he says these heads came factory on the 2005 cvo. Does that help?

 

Online it says 95 cc

 

That 88" will have at/near 8.0 cr.
With that cam, about 7.0 corrected, as that cam bleeds about 1 point, with a ccp of near 140-145.
Not trying to say it'll run terrible, but it'll run terrible.
Here is a rock-solid combo;
Our Stage I Heads
Andrews 21 cams
Bore to 98".
9.7 cr
You'll have a ton-o-fun with this.
