I'm going to pull the heads off this 455 here soon and do some much needed top end maintenance. The motor was built years ago by some shop down in Texas and runs good, but there are a few problems which have developed over the years, which the previous owner passed on to me: leaky valve covers, leaky valve stem seals, and carbon buildup in the combustion chambers leading to dieseling on hot shutoff. Probably plenty of carbon to be found in the valley area also, I'm guessing. All that plus the leaky header gasket on one side.
So I'm just going to pull the heads off, refurbish them, and solve all these problems in one go. Maybe do some port work too while I'm in there, because why not? At 10k feet in the mountains she could use a little extra grunt.
I'm just wondering if there any known snags or potential trouble areas in the head pulling process on these coaches that I should know about before getting started. Thanks for any advice.
