Well, I got the heads off today.
The passenger side head came off with the exhaust manifold on very easily.
The driver side head, well that with swivel sockets and 2x4's to help adjust the head to get to bolts, I got the exhaust manifold off. Will be a PITA to put back on.
Tomorrow morning they will go the the machine shop.
I posted some photos of the block. The motor had a lot of sludge. The previous owner said he changed the oil when the computer told him to with only synthetic oil. Yuck!!
