why the hemi heads are the better ones. better flow rates aswell. u got any local scrap yards near u? if i were u i would rip the head off one n hav a peak at what pistons they have.

yeah the 88 head allegedly is a rare find, although there is no difference between that and a 81 hemi off an injection, the only difference they are thought to have if any is the valve seats. where did u get the head from as thats the head that was fitted to carb models that didnt go leanburn
