Features and Benefits :
The RBB TSX heads have the smallest port and least material available for machining when compared to the other K-Series castings. This port was designed to fit in this casting, and takes a mediocre 275cfm cylinder head and transforms it into a 340+cfm race winner!
Slow-cut precision 5-axis cnc porting, second to none on machining quality.
45 degree valve job designed for long life and durability.
Unique power producing exhaust port design.
Smaller intake port volume, high air speed port design.
Optional full length bronze manganese valve guide for valve stability.
Port walls are left extra thick for high boost applications when used in other castings.
Our heads are all shipped with installation tips, a sheet of desired clearances for setting up your engine, and a flow chart from your head
*Message us if you have a core, we can reduce the cost but you will have to either bring us a head core or mail it in at your expense
