Default heads question need answer soon

im building a forged ls1 that will have a F1 procharger on it, i have a buddy who is offering a set of stock 241 heads for cheap. would it be worth it to get these and is there anything i can do to them to get great flow out of them and see good gains on the motor or for my setup would it be better to just get a set of aftermarket heads.

setup is aiming for 600+rwhp on a forged ls1 with blower cam and F1 procharger

Not really those heads are not really a good stock head unless worked over. My advice if you have the change call TSP or other vendor here and get a set of trick flows or afr heads. If not AI ha one of the best cnc programs for LS heads, you could send yours their.

Get some 317s and have them sent off to someone like AI for a valve job and spring upgrade.
