Ultima Performance TC Heads with Valve Covers and 3.875" Bore Cylinderssed
« on: April 10, 2014, 12:23:13 PM »
Has anyone used the Ultima TC heads or cylinders? What are the head CC's? My son has a stock 80" EVO and bought some TC parts a few years ago. I am considering building him a 100" Fatso Motor for his 94 FXSTC. I am looking for any insight on anyone with any of the Ultima TC heads or cylinders or the Fatso Gen 2 (Cases/Crank/Rods Assembly) that uses the TC .972" wrist pins Wiseco 3.875" forged pistons. I know the cost will be as much as an assembled Ultima motor but I kinda like it. TC spare cylinders and heads are cheap if ever needed years from now. I know the TC pushrod holes in top end need reworked or use Sputhe tappered pushrods.Any insite? Thanks

I've used the Ultima heads. Very good bang for the buck. They flow good air, chambers are big( right at 99cc), and like anything else, can also be improved on. The "Fatso" build should rip if you get the compression and cam right.  ;)
