The K1 rods look to be the best set, just keep in mind they are 198 length rods, which will raise your compression to just over 10 to 1 and will be a little much for a turbo application. Marshall at Campbell enterprises said getting custom pistons to lower the compression for a turbo application would not be a problem, but it will put you up to about $718.00 for the set. In considering a turbo app he also suggested upgrading to a stronger pin as well. This for me is fine, though it will take a while to put $$$ aside because I'd like a strong rotating assembly to handle the pressure.
The Cox Bros. used to have a roller tip rocker assembly available from what I understand(I'd like to know more about that myself) and SI Valves has a larger valve for the slant. The important part to me is finding a machinist to open up the breathing capabilities of the slant 6 head.
And if you find anyone who has or can fab up a decent turbo header I wouldn't mind knowing about that
