Need/Want some day 2 insight...

[72LS5]

Found a deal on an engine that I couldn't refuse. Going to toss it in my 69' Malibu for now to get it running. It's a C 15 73 dated 290 casting 402. Has 67' dated 390 casting oval port heads. Tall, finned aluminum valve covers, what appears to be an 3885069 intake - casting #'s, etc have been ground off an it has been polished. I also found a set of headers with a square, 4 bolt flange. I am going for a day 2 look with the engine. What should I do with the intake? I was thinking of blasting it to make it look rough cast again. What about the valve covers? Keep them polished? Or black wrinkle paint with just the fins polished? And what color heat paint on the headers?

I am going to run stock brackets and pulleys. Top it with a 750 holley I have laying around, and a factory open element air cleaner I have. It will be backed by a 2.64 1st geared super T10 I have kicking around, and the factory 3.31 posi 12 bolt. Going to look for some vintage wheels of sort to throw on it as well. Should be fun until I have the time and cash to build it exactly how I want it.
