I used to run the L79 cam in my 68 L30 327, but a couple years ago went to a Comp Nostalgia 30/30 Hydraulic cam. I have a 69 over the counter aluminum intake and holley carb on it as well dressing the whole thing up like a 302. Setup runs decent, though it could use the pop up pistons instead of the stock flat tops, which i'm looking at installing soon. As stated earlier, just swapping a 2.02 valve into an head that was a 1.94 does not gain anything. I know recently, I think Trick Flow, started making a aluminum head that looks like a factory camel hump head with casting grain and the mold seam down the exhaust ports. The only real change from a GM head was the valve cover gasket surface was a little higher. You could paint the heads and know one would really know the difference. But swapping the heads would probably need a set of headers, which there a few sets out there that look like the stuff you would get in 69 as a day two item and would not look too out of place.
