425 Build
Thought I would start a second thread on the engine build for the Riviera to keep things sorted out a bit.
The motor is going to be mildly modified. It has been cleaned and "Glyptaled". I think this will be the only Nailhead I ever Glytal, it is such a complicated block and I think pretty much impossible to cover completely!
I am struggling with cam selection, so I have put most of the cams I found on the Nailhead Cam specs page located here:

Some grinds, I did not find on the manufacture's websites, only on ebay, so they are linked there.

Piston Coatings
I wasn't going to do any coatings on the 425, but I had to do some for a sbc stroker, and figured I might as well to the Buick too! I think that may mean I am starting to slide down a slippery slope. Where do you draw the line: Internal engine coatings by Tech Line Coatings

Bob, those look so very nice . Have you figured out a cam yet? One of the TA aftermarkets will probably fit the bill, but some of the Nailhead performance enthusiasts like the comp extreme energy cams.

I am probably sticking to a mild cam, I want a comfortable cruiser. I do have a Schnieder on the shelf. It has valve lift of .464 and .477 and .050 of 205 and 215 and lob separation of 112. I know its not what most would want, and I could go a little more, but the car is a full load with a/c and I want it to drive nice. I know much of what I am doing would normally go with a lot more cam, but I am not sure how happy I would be with much more.
My GS 400 will get more when I do it's 455.
The coatings I use are Techline. I am not sure if you have to qualify as an automotive related business to purchase them, but there are some retailing kits on ebay. Click Here...

Finally got back and did a few more things on the 425. The Crank is in, maybe tomorrow I will get the piston rod assemblies in, maybe...
The Crank is in, and the heads are almost ready for assembly. All that has been done to them is, intake guides go major tapering to the valve stem. Real "uglys" removed from the runners, multi-angle valve job, back cut valves, increase valve reliefs, radius-ed combustion chamber corners, and CBC-2 Thermal barrier.

Bob, what cam shaft did you decide to use? When do you paint the outside of the block?

The cam choice will be a disappointment to almost everyone. It is a Schneider:
intake: .464 valve lift, 205 @ .050"
exhaust: .477 valve lift, 215 @ .050"
112 center
Paint is on:
