Ok, I just read through the thread in the link. Seems Ramm re-worked the valve job, port, and shrouding ??? I'm not paying 1450 bucks for a set of head, then having to pay a machine shop to do an adequate valve job, and such. If I'm paying 85% of a set of TF's, then I'll buy the TF's. If I buy any head, they will have to work OOTB. I can do some things at home with my dremel, but not a "new 5 angle valve job".
