H-I-J '76 Nova re-fit.

Cast iron heads rust very quickly and easily especially around the exhaust valves. All the after race smog techniques mentioned are good. One more that helps is to cap your headers at the collectors. The plastic caps used on threaded pipe works well if you can find a size that fits. Large Electrical conduit or black pipe sometimes has caps that fit. My buddy was an electrician foreman on big jobs and had those caps off his job sites.

Yes, the rust was everywhere but worse near heat, around the plug and exhaust valve.

Everything is cleaned, heads are back together, crank is in the block.

Rods and pistons are in, heads are on, studs and guide plates are in.

After awhile you'll notice main cap walk even with studs.Only cure is 4 bolt mains.

My initial plan was to use this one as a spare, at this point I'm wondering if it will ever run long enough to even be that.
