Well, just a quick update. I have this small block 400 in a machine shop, and have replaced the block, reusing the crank, and ordering new pistons. I did find out that the heads on this engine are not reusable. Any advice for replacement heads, from reading on here I have heard good things about Vortec heads. My intent is to build a strong and reliable motor, that is above average or stock specs. I won't be racing, but some trailer towing, and fuel consumption is important too. I could use as many suggestions as possible, such as heads cams pistons etc.
I have found a set of 400 heads for only $50, but will spend extra to go to Vortec heads if it makes a big difference...
