TBparts V2 race head, intake manifold, and stage 4 camshaft TBW0577. This kit is only for use with a matching TBparts piston. We also do not recommend the stage 4 cam TBW0577 with any setup smaller than 155cc

The TB V2 Race head has numerous advantages over the stock head. Starting with the addition of forged aluminum roller rocker arms and our V2-2 stage 4 camshaft. Not only do the aluminum roller rockers free up big horsepower, but you can also run much more aggressive cam profiles with roller rockers for even more power. Next is the bigger valves 30mm intake and 24.5mm Exhaust. The intake and exhaust ports are equally as improved at 27/23mm. Both valves are stainless steel too (21-4N material). The valves also come installed, complete with high lift heavy duty valve springs. This all adds up to a cylinder head that puts out a professional level of performance and power yet is still affordable for the privateer rider.
