yeah no highjacking but A LOT of my ?'s have been answered in this thread. thanks guys. i too was have that same leak. i thought it was coming from there but couldnt see how from under. i replaced the dist. o ring twice thinking the first was bad. i will wait to replace my gasket until i get my 4.3 tb. From the looks of it is the holley upgrade larger than the stock 4.3? and are the roller rockers a drop in install?
