L98/LT1 head cooling patterns....
I have an 89 block, 4 bolt main, truck OEM issue......rebuilt, and have been running aluminum GM heads ending with #113 on the casting number under the cover.....
So just what is the plumbing/water flow for these heads?? I assume the two fronts go through the typical stat and to radiator....how about the two rear?? gaskets seem to have very small holes in that spot, like near zero water flow.....reason??
and just what is the diff in water flow patterns between an L98 manifold and say an earlier LT1 manifold??
OLD hotrodder here, having an issue, and I suspect this is part of the problems....
