Description

The Tillotson JT-207 has been modified from 25/24mm to 27/25mm diameter valves and 5.5mm to 5mm valve stems to improve flow. 

This head is the same used on the Tillotson 212R and coming 225RS engines. This makes a great replacement for the Predator Hemi engines gaining as much as .6:1 compression from just changing heads. Typical Predator Hemi is around 8.2:1; this head will bump it up to 8.81:1.
