SignUp Now!They are 23 degree heads. Brodix makes a -8 and a -10 version of the head. The part number on the head should tell what they are.
-8 heads have 194cc intake port and 67cc chamber volume. Minimum compression is 9.1
-10 heads have 210cc intake port and 67cc chamber volume. Minimum compression is 11.5
For a turbo motor in a sy/ty you would want the -8.
i don't understand..i would want the -10's , they flow more..........Bob
