Ok..I have my engine is tore most of the way down..still have the rear head and manifold on(closest to the firewall)...I bought a set of heads from someone here on the forum. Those heads are in the machine shop, I can't get my hands around the back of the bolts on the downpipe(I think thats what it is)...how can I get that off and get to the rear head while the block is still in the car? Also, before I put it back together I want to get all the grime and gunk off of the block..what is a recommended way to go about that? Thanks
