Mike, I would stick to the 9333pt1 gaskets. The cosmetics are great and I swear by them on my motor but in a build like yours the head gasket can act as a fuse @madspeed. If something goes wrong, mechanically, tune up wise etc the worst you'll do is blow a head gasket. I have literally melted a hole out the side of a cylinder head running a cosmetic and having a mechanical failure. As for the rest of the parts, it seems to be pretty comprehensive. I would rather see head studs than bolts but that decision is yours. I'm not a Huge chrome valve cover fan myself..they always seem to leak but that's my .02¢
As for a timing chain, any good double roller will do. I personally always stuck with comp cams.
