Question please. Would the 3.937 piston need to be domed, in order to get to 10:1 compression, using the original CVO script heads (approx 95cc chamber)? If so. How much dome would be required? i have been kicking around this 103 to 107 move for awhile. Thank you!
To match the chamber at 107" would take a custom dome to get the thing working right or a flat top and milling to give the hemi chamber s perimeter squish area

Allot of guys I've been working with are opting for the 110 kit and the more traditional "bath tub" head.
Find a set of silver -06 heads (plentiful), machine them for ACRs and Bob's ur uncle!

127-130 squared is pretty common using a 590 Tman cam set or something similar and a decent pipe. Don't
be afraid to ditch the 103 CVO heads! Finding pistons for them is a pain in the butt. Get rid of them and piston
choice becomes a non issue.

HD Street Performance. Would the Arias piston at 3.937 work? Description reads for HTTC / CVO HEADS 99-06. 
https://ariaspistons.com/products/twin-cam-88-1999-2006-103-ci-3-885-10-5-1  Is that a recessed dome piston? Thank you for the information!

Yes of course and that would be expensive, custom, require 4 made, or pay some more premiums.
