[tab title=”Description”]
BRODIX offers several versions of -10 CNC ported, raised intake runner 23° heads ranging from bare castings to completely assembled packages.
Combustion chambers are available in sizes from 56 cc – 74 cc. Valve sizes range from 2.100 to 2.125 depending on bore sizes and valve centerlines.
The deck surface is the strongest in the industry allowing the use of nitrous and blowers. Hardened valve seats are standard allowing use with unleaded fuels. Phosphorous bronze valve guides assure proper valve guide wear.
