heads
If water is freezing before it hits the ground and you only have high 9's maybe 10.1 comp w/aluminum heads and it's a street car/daily driver.....
Just run iron heads.jmo
And for those who think eddy heads are better than mopar heads, you must of not run w2's before.
Eddy's need to be around $950-1000 a pair for the lil they offer untouched.
