Everyone else asks, (512 build) why not "ask the forum", lol
I just assembled a 440 based 493 using trick flow 270’s and the Indy dual plane intake. My particular intake was cast really nice, only needed minor gasket matching and will just barely clear the hood on my 71 demon with a drop base air cleaner.
In regard to your camshaft, I would look for something with a little more duration at .050 if you plan on spinning it over 6000 RPM. My “streetable” solid flat tappet comes in at 275 at .050. and is spec’d for shift points just over 6000 RPM.
