The idea of stuffing the 27 block w/a longer arm and pistons to match the CR and the stroke is a sound approach IMHO.
In that car, reusing the fuelies would look right, Vortecs will run better, your choice.
Using styling cues from that era on the engine (finned aluminum v-covers, a front-mounted oil fill tube, things like that) will offset any loss of "the look" from using different heads to some extent- but fuelies will be the best for popping the hood at the Steak & Shake.
If the intake has the U-shaped heat riser channel, be sure you use the right type of stainless steel clad gasket between the intake and carb.
Nice looking car, BTW. Good luck.
$400 is more than the local salvage yards charge, including warrenty. As far as looks, a little orange paint goes a long way for 99% of the people out there. And finned valve covers and such will really be what draws the eye, not the casting symbol on the front of the heads.
