Features of this kit:
     -Race Head V2
     -Race Camshaft with high lift & longer duration
     -Larger intake manifold

While this head may appear to be the same on the outside as the previous TB race head that was discontinued & stock heads, internally it’s has numerous differences.
The addition of forged aluminum roller rocker arms and a new race camshaft are the biggest changes followed by bigger valves and ports. The exhaust valve (like the intake valve) is now also stainless steel made of 21-4N material. This all adds up to a cylinder head that puts out a professional level of performance yet is still affordable. The kit also includes an all aluminum ceramic coated cylinder. This cylinder is lighter than a steel sleeved aluminum cylinder, reduces friction (increasing power), improves sealing, and provides better heat transfer (runs and cools down quicker). In 2020 we upgraded the piston for higher compression and more power. Unlike other kits, our head gasket kit also includes a head o-ring set and exhaust gasket so you don’t have to re-use your old ones or make a trip to your local dealer to get new ones and spend more money. These are high quality parts and require no machining to the cases or other modifications – bolt on and go!

Add a stroker crankshaft for even more power! (Just call and a rep can make sure you get what you're in need of)

These parts are installed in the same manner as the OEM parts.
