I inquired with Kaase the reply I got was I need custom pistons so if its a new build probably not much differece in cost . If you want to bolt on and go , just wont happen . It seams any really big flow head is about the same cost 2k + . Now I'm going to re read the threads
I remember all the problems Tick Flow had with valve guide wear when they first released the Twisted Wedge head. I would like to see some long term reliability tests conducted before I spent that much time and money on a build up using those heads.
