I have a bare head with cam journals and locks for sale. It came off of a pro level tt quad. Ported by TC Racing. It has TC National engraved in the head. I took it off of a running engine. It doesn't have valves or cams but if you have a stock head you can swap out the valve train and see some significant power gains, I will post pics tonight.

$350 or best offer

Anything wrong with head? Still using stock size valves?

I bought a complete TT race quad from a guy in New York who raced the NEEDTS. He has always had TC do all his work on the engine. I am sponsored by Matczack Machining and they do their own porting. We took this head of of the quad in running condition. I was going to sell it complete but we found that the cam had significant wear and one of the valve springs had broke. Therefore I scrapped all of the valve train. The head uses stock valves. So if you have a stock head and you want a bit more power you can take all your stock stuff from your head and put it in this head and it will definately breathe better than stock. It has also been cleared out to accept a large lift cam, as that was what was in it. It's a TC NATIONAL.
