yes needs indy 600-13 or heads designed for that bores space. the motor will make some serious power so , not sure what you have now but more may need to be upgraded in the car. Even if you end up not using it, it can be flipped. For good info, call Chuck at Best Machine. They have built a few of these 4.84 bore spaced engines and im sure he could fill you in. You can build big cubes as that block can go 4.60 bore
