head?
 

how much better is Brodix 10x heads over Brodix track1's? are the 10x 18 degree? what will i have to change to run them? thanks Avery

anybody? which head will make more power

If the motor is built with high compression and a larger cam the 10x will make more power. The 10x also uses different rocker arms and if it is the 10xri it will need a raised runner intake. What are you trying to do? Do you already have the heads? Also the 10x is not a 18* head.
