I just used a production 340 head and did the port work to it and a new valve job I want to try on the street. I think it's reliable. Most don't. I would have to pull the engine file and look at the head CC's but IIRC they were 73. I used the TRW L2322 piston and milled the dome down until I had about a net 6 CC dome, IIRC.
The cam is a custom Racer Brown grind that Jim and I talked about for a long time. I'll post the grind number later but it's 255/255 @ .050 and 283/283 at lash. .620/.620 gross lift. It lashes at .014/.018 hot. It's ground on a 105 LSA and installed at 105. There is a start up video on line somewhere. Damn if I know how to find it.
