A diy is a bit rough I think for this, since I think you really do need to have a good mechanic background. There were several places where one little mistake would have caused billman to take apart the rest of the engine. Then again if you have all the time in the world... I'm sure anything is possible. Billman did mine in 2 hours flat =p.

You need an air compressor. You need a leakdown tester. You need a valve spring compressor that actually fits. you need to have the skills and tools required to remove the camshafts and then replave them again.
It took me more like two months than two hours (usually working only for several hours on weekends).
There are some specialized tools that would have made the job a lot easier.

it would be great if billman could chime in and let us know what spring compressor would work for this job,
iv only done valve springs on a chevy head with the head off the engine

I'm not billman but this is what he has and what I have too. You have to grind the metal ears off one side to make it fit better.

I am also curious to using the Ap2 retainers and what the actual weight difference is befoer i replace mine
Bill, have we actually seen cars dropping valves without ever having been over reved?

Bill definitely has a great reputation and i trust his word on using Ap2 retainers in an AP1, im just curious how the extra weight would effect the margins at redline, and would he recommend some stiffer springs to add alittle buffer?

I did all of mine in 4 hours (just replacing the springs and retainers, not including all the head dis/re assembly).

That particular tool was fine for the OEM springs, but it sucked for the dual springs I replaced them with. It would keep slipping off the inner spring coils.
Also, I did it by myself, and the big hassle was getting the cotters reinstalled. If I had had just a third hand available (or if the spring compressor would have worked better on the dual springs) it would have been much easier.
