I know before, when I was just a visitor, I saw a post in regards to someone that had built head packages for the mazdaspeed. I must have lost the contact on that company. But if I could get a head for under $200, even with the cost of building the head would be far less than going through that company. The parts that my local was going to use was s.s. valves, bronze valve guides, street/strip port, valve job, bowl and gasket, surfacing, cleaning of surfaces, and disassemble/assemble of head, cost-$roughly $1200. My 2 problems are first, locating/purchasing the head, and second (which is actually to me more important) to find good turbo cams. The only reason for the cams being a vital part of the headwork is that I don't have a lot of downtime to spare, and I would rather pay the local since I'm paying for assembly anyway.
