Cam advice for ill advised 318 combo?

I plan on building an engine from "shop sweepings" I know it's less than ideal but I know someone has been there before me and found something that at least sort of works so here goes.
Parts list:
Stock '73 318 short block 50K miles can still see cross hatch in cyls
Stock '69 J heads W/ 202 intakes. aftermarket stainless valves
Stock rockers or 273 adjustables
Edelbrock Performer intake W/ Thermoquad


Now I know those big valves are going to bleed off a lot of compression and I didn't have enough to start with.

Any cam suggestions for this combo? Fess up I know someone here has done it before!!

Or am I better off with the 2bbl cam in it now?

Headers or stock manifolds?

I know this is less than ideal and I intend to move the top end to a 360 eventually but I would like to drive the car in the meantime..

Am I nuts?? or will it be such a pig I should find a 2bbl top end for it?
I hate to buy a cam I cant reuse but buying heads/intake /carb I wont reuse seems like an even bigger step backwards.

Thanks, and don't hate me...
