Do the screaming eagle heads that are equipped with electronic compression releases compatible with twin cam 103 with thundermax.

cheers HBP.

have you got more info on the heads m8? but they should work ok as long as the combusion chamber matchs your pistons

 G Day Krash the heads are off a sreaming eagle cvo 110 engine if that helps.

Hi Hell bound, well m8 the 103 inch is actually same bore size as the old 95 inch twin cam just the 103 has slightly longer stroke, i think the 110 inch is 4 inch bore same stroke as your motor, but as far as i know they still use the same stud pattern same size studs and same cases. i think they use a larger intake valve that just over 2 inch. i think you would be better off pricing the 110 barrels too, if you can do your own work, i know a guy in Sydney that has a bridgeport mill set up just to do the cases resizing job on twin cam cases. he can also deck the barrels if need to close up swish band ( gets piston to come up higher in the bore). if you don't feel ike going to all the trouble, just hang onto those heads if you have them, keep an eye out for barrels & pistons for latter on. as i don't think you would get much benifit at all just bolting it on as is.

good luck.

ps, about the Thundermax, i would expect it to work fine, but you could ask Ozrodder or Scotty i have not played around with HD EFI but have some mates that do and they get good results, but only have one mate with Thundremax he was having pinging problems with a hi po setup, then bought an RB Racing pipe and it came with a map for the thundermax and it runs good now , i have not ridden it but he told me its sweet now.
