polish the rods and add arp bolts and resize.. maybe bush the small end.
spend your money on good pistons and roller cam..
bbc rec port heads off a 454 or even oval ports will do . no need to spend big money on new aftermarket heads..
if it was me, I'd look at the date codes on the block and head you have..
and the engine code and maybe sell it to a guy thats retoring a car that needs a correct date parts..
then get a 454 and build it or make a 489/496
with the money you plan at throwing at the 396 with all new parts you'll still only have a 402.
if hell bent on the 396, you don't need new parts, use whats there.. get good 454 iron heads and rebuild them.. no need to drop 2000.oo on alum heads for a 396.. of $$$ crank/rods
it's a little odd that you are say'n 454 cores are costly but want to buy 2000.oo+ heads and 1000.00 in roller cam+ new crank/rods ect into the 396
my 454 was 800.oo but it was a running fully dressed engine..
