It was listed at Summitracing.com. Only diff I saw was that this head has 72cc chambers. They are listed as bare or assembled. I actually just called Summit and they said that Trick Flow was actually owned by Summit. They said the 72cc heads were special order and would take 2 weeks to get, so maybe they are NOT new? Anyway, 72cc heads are the ticket for me

It is either these TFS heads or old CJ A429 heads. I think ported, the TFS heads win out...??
