Stock 302 ain’t a 400 hp head even the stock 1.88 J heads won’t get you there,
Your either need to port the heads for the power level you want or cheaper to buy aftermarket heads especially if you got to get someone else to do the work.
2.02 are fine with a 318 especially after boring your not that far from a 4” bore.
