roller rocker help
for cheap from work (on clearance) I looked them up in my computer at work (checkers) and it said that they would work for my car 94 lt1 bird.
i get online after work and see that they "will not work on centerbolt heads" and that they are NSA (non self aligning) (are our heads SA or NSA) are these possible for me to run? and i dont mind clearancing the valve covers.
i know that these are stock ratio and that i will not see the gains of going to a 1.6 but i figure that i will see gains from the rocker being full roller (hopefully a few hp.
