Going To Do Some Major Rebuilding. Need Sources

[DT1]

71 C-10 350/350 Q-Jet
I'm pulling my engine, and transmission out of the 71 this weekend and will be rebuilding everything stock.
While I'm at it, I'll also be rebuilding my Rochester 4bbl.
Can you guys suggest a quality, full engine gasket set, transmission kit and carburetor rebuild kit. I've had problems with inferior stuff in the past and I really want to avoid it this time. I've always used Felpro Perma Torque gaskets with good results but one of the ongoing problems I've had is with the valve cover gaskets leaking. It also seems that there are a lot of bad carburetor kits out there.
Thanks for any suggestions!
