I figure removing the cylinder heads would be a real pain and expensive, I talked to a couple machine shops and they quoted $3k for rebuilding the heads. Online retailers want $5k. When I got the car it had 119k miles and needed the timing chain and guides replaced. I did that all myself and it took an entire weekend (20+ hours). I would have to do all that again and add removing the CIS fuel injection, intake, and exhaust all of which have not been disturbed in 30 years. When I have worked on that part of the engine in the past the connectors and rubber just crumbled...
