Another 273 question

I'm here at FABO because you know your 273s. I have my 65 Belvedere wagon with a 273/904. I am looking to do the top end this winter. Nothing radical. Bottom end is fine, good oil pressure and no smoke. What are some good vendors for 65 273 parts? I know about the different head angle from the 66 and later motors. It's a driver and may tow a tiny camper in the future. I'm looking at cam, lifters, timing set, oil pump, rockers etc. It really runs great but it likes to leak everywhere. Gaskets and freeze plugs. I figure if I'm going to pull the motor, I might as well do the top end.
Also need a 904 filter and gasket for the 65 tranny.

Also for $hits and giggles, how about a 4 barrel intake and carb? Stock cast iron is fine so I supposed a little better cam would be thrown into the mix. Anyone run 273 headers on their B-Body?

I've tried to contact Joe Suchy but I'm getting no responses. Thanks
