Stus-List 3QM30 Head Gasket

I had a similar experience on my old 3QM30. Removing the head is not difficult and there isn’t much interference on the engine. On my C&C 36 the difficulty was the lack of space to lift the head. To remove it I had to remove the head studs from the block and then slide it forward. I went the cheap route and just replaced the head gasket. A year later I updated the engine with a new YANMAR. I’d get an estimate for both removal and the service work on the head and the injectors. If you save much then remove the head yourself and deliver it to a machine shop to rework the valves and injectors. Lastly my 3QM30 was raw water cooled and many of the water passages were clogged. I was able to rod them out without removing the engine.
Feel free to contact me off list if you have any questions.

I think the price is fair but I wonder if I could do it myself. Anyone have any experiences around this? I am a fair mechanic, but I don't want to be penny-wise of pound foolish and I have never done anything like this before.
